Add onion and mushrooms and cook until tender.
Add garlic and cook for one additional minute. Then, remove from heat.
In a medium sauce pan, heat olive oil over medium heat. Mix in the chickpea flour, garlic powder, and sea salt, stirring constantly. Cook for one minute.
Add the almond milk and stir to combine. Continue to cook, stirring very frequently, until mixture has thickened.(To get even thicker, can add 1 tsp. arrowroot starch, though this is not necessary).
Add in 3/4 cups of the cheddar cheese, and stir until melted.
Sprinkle the remaining cheese evenly over the top.
