In mixing bowl, combine ingredients for gremolata and mix well. Slice olives in half (option to remove any pimento/stuffing), and adjust salt and pepper to taste. Set aside to let flavors absorb, especially the red pepper.*This could easily be made ahead of time! In a stock pot, steam or boil cauliflower florets and drain. Use a paper towel to absorb remaining moisture and put back into stock pot.
Add butter, salt and pepper, and using immersion blender, puree. Cover with a lid to keep warm.
Heat skillet fairly high and add pine nuts, tossing often to create an even toast. Set aside.
In skillet, sauté carrots and onions in butter and olive oil and turn heat low. Slowly caramelize them, constantly stirring and adjusting butter and olive oil if needed.
When carrots and onions are tender, add a dash of nutmeg and fresh basil leaves. Stir to incorporate.
In air fryer or oven, place tilapia filets on a sheet, season with salt, pepper and paprika, and bake thoroughly.
Serve cauliflower puree with candied carrots over, aside a tilapia filet topped with gremolata. Sprinkle toasted pine nuts. Garnish with a sprig of fresh basil or dill and a wedge of lemon. Enjoy!
