1 head cauliflower chopped into bite-size pieces
2 packages cauliflower rice: frozen, 24 ounces (or use your own fresh cauliflower rice)
1 to 1-1/2 pounds chicken leftover or already cooked, chopped into bite-size pieces
2 cups heavy cream preferably raw, ideally not ultra-pasteurized (for GAPS: Use half coconut cream and half fully cultured sour cream, 1 cup of each)
8 ounces brie or cream cheese, cut into 1" cubes (for GAPS: Use brie)
8 ounces cheddar cheese or other aged cheese
1 package bacon about 8 ounces, cooked then crumbled, save the fat for roasting the cauliflower
1/4 cup gelatin see discount code! and link in Recipe Notes
3 tablespoons bacon fat rendered from cooking the bacon
3 teaspoons sea salt divided
1/2 teaspoon freshly ground black pepper or white pepper (which is lovely); see Recipe Notes
1/2 bunch green onions greens only, chopped small for garnish

Preheat oven to 400 degrees Fahrenheit.
Place 3 tablespoons rendered bacon fat, 1 head of chopped cauliflower and 24 ounces cauliflower rice in roasting pan or casserole dish. Add 2 teaspoons sea salt and toss to coat. Roast cauliflower in preheated oven 30 minutes.
While cauliflower roasts, make cheese sauce in blender: Heat cream in small saucepan until hot; but do not simmer. Remove from heat.
Place brie or cream cheese into blender. Add remaining 1 teaspoon sea salt. Pour slightly cooled hot cream over cheese and sea salt. Sprinkle gelatin over all. Use caution when blending hot liquids: Turn blender speed to lowest setting. Blend on low speed about 10 seconds then increase to medium speed for an additional 10 seconds.
Remove roasted cauliflower from oven. Add chicken, cheese sauce and pepper, using spatula to scrape cheese sauce from blender (it's thick). Use two spoons to stir together (right in the casserole dish) cauliflower, chicken and cheese sauce.
Smooth the surface. Top with cheese. Return casserole dish to oven for 20 minutes, until golden brown and very bubbly all over.
Top with crumbled bacon and green onions.
Allow casserole to set up 15 to 20 minutes before serving. Serve!
