For the homemade tortilla chips, heat 4 tablespoons of oil in a large skillet over medium-high heat until shimmering. Add about a quarter of the tortilla wedges and cook, flipping once, until lightly brown and crisp. Drain the freshly fried tortilla chips on a paper towel-lined baking sheet. Sprinkle lightly with salt. Repeat this process until all tortillas are fried, adding more oil if needed.
For the sauce, place the tomatoes, onion, jalapeño, and garlic in a blender or food processor fitted with the blade attachment. Pour in 2 cups of the broth. Blend until smooth.
Heat 1 tablespoon oil in a large skillet over medium-high heat until shimmering. Add the sauce and cook, stirring occasionally, until slightly thickened, 5 to 10 minutes (the consistency of the salsa will vary depending on the size and juiciness of the tomatoes). Add additional broth to thin out the sauce, if needed. Taste and season with salt as needed.
Add the tortilla chips and stir carefully to coat the chips. Cook until the tortillas are heated through, about 3 minutes. Taste and season with salt as needed.
Serve warm garnished with the roasted pork, avocado or guacamole, crema, queso fresco, cilantro, and/or fried eggs, if desired.
