Preheat oven to 350°F and grease a 9×13" baking dish.
Sauté the aromatics: In a pan over medium heat, cook the avocado oil, aji peppers, onion, and garlic for 8–10 minutes until softened.
Blend the sauce: Transfer cooked ingredients to a blender along with tofu, turmeric, soy milk, coconut milk, cashews, crackers, nutritional yeast, and salt. Blend until smooth.
Cook the pasta: Boil in salted water, drain, then return to the pot. Stir in the sauce and 1 bag (8 oz) of shredded cheese.
Assemble: Pour into the greased baking dish and top with remaining cheese.
Bake for 25 minutes until hot and bubbly, then broil for 2 minutes to brown the top.
Serve warm. Store leftovers in an airtight container and eat within 3–4 days.
