Place a large pot over medium heat, add EVOO. Add the onions, garlic and jalapeño, and season with coriander, cumin, salt and freshly ground black pepper. Cook until softened, about 8-10 minutes.
Add the tomatillo salsa, chicken stock and hominy to the pot and bring to a bubble.
While the mixture is coming to a bubble, place the tortilla chips (reserving a handful for garnish) in a food processor and pulse to grind, or in a resealable plastic bag and crush with a rolling pin or empty wine bottle. You should have about 2 cups of ground chips. Add the ground chips to the mixture and cook for 10 minutes.
