Start by gathering all your ingredients. Chop the tomatoes, scallions, and any other fresh toppings you plan to use. Prepare your taco meat if making from scratch.
Preheat your oven to 350°F (175°C) to melt the vegan cheese perfectly without burning the chips.
On a large baking sheet, spread out a generous layer of tortilla chips evenly to avoid bare spots.
Spoon the prepared taco meat over the chips, spreading it evenly.
Generously sprinkle vegan cheese over the taco meat and chips. Use multiple types if desired.
Bake in the preheated oven for 10-15 minutes, until cheese is melted and bubbly.
Remove from oven and add fresh toppings: chopped tomatoes, pico de gallo, scallions, and sliced jalapeños or serrano peppers.
Add slices of avocado or dollops of guacamole, pickled onions, radishes if using, and sprinkle with chopped cilantro.
Serve with lime wedges on the side for a fresh, zesty squeeze.
