To your blender, add the nutritional yeast, sunflower seeds, rolled oats, tapioca starch, garlic powder, onion powder, salt, mustard powder, paprika and turmeric powder. Process until it becomes a fine powder, about 20 seconds.
Add the water, red bell pepper and coconut aminos to the blender and process until smooth. Transfer the mixture to a saucepan and heat over medium-high heat. Cook for 7 - 10 minutes, stirring often. It will slowly become thicker and thicker. As this happens, begin to stir constantly until it's thick and gooey.
Remove from heat, cool to room temperature, then promptly store in your fridge.
