1. Preheat your oven to 350 degrees and lightly spray a casserole dish with olive oil. Add cauliflower rice to the bottom of the dish and sprinkle with a pinch of sea salt.
2. Next, add the chicken and, again, sprinkle with a pinch of salt. Add in broccoli next. Set casserole dish aside.
3. For the cheese sauce, in a large skillet, melt butter over medium heat. Sprinkle in the flour and whisk together. Slowly whisk in the almond milk, and continue to whisk until the mixture comes to a boil and begins to thicken. Once thickened, remove sauce from heat and stir in 1-1/2 cups of cheddar cheese until fully melted, adding salt to taste.
4. Pour cheese sauce over casserole, using a rubber spatula or spoon to spread out the cheese. Top with remaining 1/2 cup cheese and place in the oven for 45 minutes or until cheese starts to bubble. Enjoy!
