While oven is heating up, cook the rice as directed for 1 cup. Set rice aside once done.
Blend all ingredients for the pineapple sauce together in a blender, taste as you go. Once done, place in fridge until ready to use.
Set up a dredging station to coat the cauliflower florets. Add the gf breadcrumbs, shredded coconut, garlic powder, and a pinch of salt and pepper to one medium sized mixing bowl. In another medium sized mixing bowl, add the 1 cup of coconut milk, 2 tbsp of tamari, lime juice, and 3 tbsp corn starch. Whisk wet mixture together.
Working one floret at a time, dip the floret in the wet mixing bowl first (the coconut milk and tamari mixture) and let the excess liquid drip off. Then dip the floret in the dry mixture (the bread crumbs & coconut flakes mixture). Lay down gently on the baking sheet lined with parchment paper. Repeat the same process until all florets are coated evenly and laid out on the baking sheet.
Place cauliflower florets in the oven for 15-18 minutes until the are crispy and golden.
While florets are cooking, slice bell peppers, green onions, and avocado if using. Set aside.
In a mixing bowl, add the cooked rice, chopped cilantro, zest and juice of 1 lime, salt, and pepper. Stir until rice is coated. Taste as you go. Divide the rice mixture into 2 serving bowls.
Divide the cauliflower florets into the 2 serving bowls on top of the rice (you can save extra pieces for leftovers). Add chopped bell peppers, green onions, and avocado. Drizzle over pineapple sauce or pour into a dipping bowl. Ready to serve!
