Start by rinsing and de-stemming the tomatoes.
Quarter ½ of a white onion. Quarter ½ of a red pepper.
Add all of this to a pot of water, along with garlic and jalapeno or serrano (if using).
Bring to a boil. After 3-5 minutes, using a pair of kitchen tongs, remove ingredients from the water and transfer to a blender.
Blend with ½ teaspoon of salt, oregano, cumin and cilantro. Combine well. Taste and adjust salt as needed. If using jalapeno, serrano or any other type of chile, add this a few slices at a time until you reach your desired heat level.
In a frying pan, heat 2 tablespoons of oil and fry each tortilla in the oil. Remove one by one and place on a plate.
In a separate frying pan, add 1 tablespoon of oil over medium heat. Add all of the tomato sauce from the blender and bring to a simmer.
Use a pair of kitchen tongs to dip tortillas in the tomato sauce one at a time, completely submerging the tortilla in the sauce. Then, remove the tortilla and put it onto a plate as it comes out of the sauce, filling with crumbled cheese.
Fold the tortilla – or roll it up – and once you have two or three on a plate, coat them with more tomato sauce.
Garnish with Mexican Crema, a sprinkling of finely chopped cilantro, and diced onion. Serve immediately. Accompany with hot sauce of your choosing depending on the entomatadas’ heat level.
