Prepare any topping that you want on them such as nacho cheese sauce, taco meat, or sour cream.
If using taco "meat" fry it up in a skillet for about 6-8 minutes until it's heated through and browned.
Sprinkle taco meat, beans, corn, and cheese or cheese sauce on top of the corn chips.
Bake at 400°F (200°C) for 5-7 minutes to heat up and make the corn chips crispy and melt the cheese if necessary. (Optional if using cheese sauce).
Take out of the oven and add any fresh toppings that you want, such as salsa, avocado, tomatoes, or cilantro. Serve immediately.
Notes
If you are using store-bought vegan cheese, cover your nachos with non-stick foil before baking or put them under the broiler for 3-4 minutes to help the cheese melt.
Only add the ingredients that you want to heat up to the nachos before placing them in the oven.
Add toppings that you don't want to cook after you take it out of the oven.
