Add the tomatoes, onion, jalapeño, garlic, salt, cumin, oregano, and broth to a blender. Blend until completely smooth. This may take a few minutes depending on the power of your blender.
Heat the olive oil in a medium skillet or sauté pan over medium heat. Add the blended tomato mixture and bring to a simmer, then reduce the heat to low and simmer for 6-8 minutes until slightly thickened. Cover and set aside.
Heat the oil in a small skillet over medium-high heat. Working one tortilla at the time, lightly fry each tortilla for about 15-30 seconds per side. Drain off any excess oil by giving it a little shake while holding it with tongs, then transfer it onto a plate or baking sheet lined with paper towels. Repeat with the remaining tortillas.
Assemble the entomatadas by dipping each tortilla in the blended tomato mixture, then placing it on a plate, filling it with queso fresco, and folding it over.
Top with a few more spoonfuls of the blended tomato mixture, then garnish with more queso fresco, Mexican crema, and chopped cilantro.
