Preheat oven to 450°F and line a large baking sheet with parchment paper.
Arrange the salmon on the lined baking sheet and drizzle 1 tbsp of olive oil over the fish. Pat the minced garlic cloves over the salmon then sprinkle the fish with salt and pepper. Bake for 12-14 minutes.
While the salmon is cooking, heat coconut oil in pan over high heat. Add cauliflower rice and cook until lightly browned. Season with salt, remove, and set aside.
Remove salmon from the oven. Serve on a plate with cauliflower rice, and sprinkle both with mango and cilantro. Enjoy warm!
