Ingredients

Create a yummy wet rub in a medium mixing bowl by combining olive oil, cajun seasoning, salt, and pepper. For the cauliflower, slice it into 1-inch thick steaks. Then, place the cauliflower steaks on a parchment-lined sheet pan, brushing both sides with the wet rub.

Bake the Salmon and Vegetables

Next, quarter the baby Dutch yellow potatoes, toss them in the rub, and add them to the sheet pan, leaving space for the salmon. Bake the vegetables halfway.  After the initial bake, season and add the salmon to the pan, flip the cauliflower and potatoes, then return it to the oven to bake.

Make the Dressing

Meanwhile, prepare a salmon sauce with Dijon mustard, honey, parsley, salt, and pepper.  Once the salmon is cooked, brush it with the honey mustard sauce. Then, whisk mayonnaise, lemon juice, and chopped parsley for the dressing. Finally, garnish the plated dish with reserved parsley.

Prepare the Vegetables

Make the Sauce and Dressing

Busy Folks - Become a better home cook with cooking tips to help you cook more efficiently on Cook's Notebook tab.  In addition, some related detailed steps can be found there.  Click here for cooking tips on prepping fish.

Substitutions

• Baby Dutch Yellow Potatoes - Use medium Yukon, russet, or sweet potatoes cut into skinny wedges to cook uniformly with the cauliflower.   One medium potato should be enough for two servings.
• Low-Fat Mayonnaise - Try regular mayonnaise or substitute it with Greek yogurt or sour cream.  Remember and don't get confused: Mayonaisse does not contain dairy, and it is dairy-free but not egg-free.  If you are allergic to eggs, try vegan mayo.
• Fresh Parsley - If you do not have fresh parsley on hand, try dried parsley or add a small amount of Italian seasoning
• Honey - Use maple syrup; however, this may change the flavor a bit, but just might work!

Change Heat Level - Modify the recipe's heat level to your liking and learn more about the Scoville Scale and Chili Pairings.  If you wish for your meal to be less spicy, try using all-purpose seasoning instead or a little bit of Memphis Rub dry seasoning.  

It also has similar spices except for the smoky component, but it may work.  And for more heat, try using hot honey, which is a prepared mixture of honey with chili peppers.

Variations

• Add More Vegetables - Try adding quartered Brussels sprouts, green beans, and/or zucchini.
• Salmon Bowl - Turn this into a bowl by making roasted cauliflower florets instead.  Then, serve the salmon, cauliflower, and potatoes with shredded greens or white or brown rice.  Try also adding more healthy protein, like chickpeas or white beans, to the sheet pan before baking.  This would be a great addition to the rice/salad bowl.

Try Something Different - Substitute the Tuna for Salmon in the Healthy Poached Egg Avocado Rainbow Tuna Salad recipe.

Equipment

• Medium Mixing Bowl - To make the wet rub, toss the potatoes and dressing to complete the meal.
• Sheet Pan - Use a half-sheet pan for a serving of two, like the Nordic Ware Baker's Half-Sheet pan. Why sheet pans?  They cook food faster than a glass baking dish.  But if you choose to use a baking dish, just watch and cook it a little longer.
• Parchment Paper - To place between the food and bakeware for easy cleanup and to prevent food from sticking to the pan.
• Turning or Fish Spatula -  To assist with flipping the delicate cauliflower and serving the fish.  Try the OXO Good Grips Stainless Steel Fish Turner.  It's just always good to have one for jobs like this.
• Brush - Used to coat the cauliflower and salmon.  I use a silicone pastry brush since it's easy to go from cold to hot meals without distorting the bristles.  Try the OXO Good Grips Silicone Basting & Pastry Brush.
• Meat Thermometer - It is always great to have to cook food to their ideal temperatures to prevent drying out.  And most importantly, to prevent food-borne illnesses.  Try the ThermoPro Digital Meat Thermometer.  To develop my recipes, I actually use the ThermoPro Wireless Meat Thermometer; it has a probe that you leave in the meat and will notify you when it reaches the ideal temperature.

Storage

• Refrigerator - To store in the fridge, you can place the honey mustard salmon meal in a shallow 2-inch container to cool down quickly. Then, store it in an airtight container.  As a result, the meal will last up to two days.
• Freezer - Follow the refrigeration process mentioned above.  Then,  place it in the freezer in a labeled, airtight container.  Be aware that the cauliflower texture will change when placed in the freezer.

Air Tight Food Containers - I use Glass Food Storage Containers with a plastic clipping lid to store food.  For example, I always suggest glass storage containers since you can microwave them and hold food without staining the container, and the glass keeps them at a more stable temperature, which keeps the food fresher longer.
