Cut tortillas into wedges
Heat oil in a large non-stick skillet over medium-high heat, about 2 minutes
Working in small batches, add tortilla wedges to oil and fry until they begin to turn golden, about 1-2 minutes per batch. Ensure that the tortillas are in a single layer in the frying pan and are not overlapping.
Remove to a paper-towel lined plate and repeat until all tortillas are fried
Meanwhile, heat a non-stick skillet or griddle over medium-high heat
Once the pan is hot, add tomatillos, onions, garlic, and peppers to the dry skillet. The vegetables should be whole, with the exception of the onion
Let the vegetables cook until the skins begin to char and blacken. Turn occasionally to allow to blacken evenly (about 15-20 minutes).
Once the vegetables are cooked, place in a blender, taking care to remove the chile stem at this point.
Add salt to the salsa as desired
Blend until mostly smooth and no large chunks of vegetables remain (about 1 minute)
Taste for salt and adjust as necessary
If the salsa is too thick, you could add a small amount of broth or water to achieve the desired consistency.
Divide chips evenly among 4 plates and top with equal amounts of salsa
Add toppings of choice (see notes)
