Heat the oil on a pan over medium heat. Add first the diced bell peppers and sauté for 1 minute.
Add onions and sauté everything for 3 minutes or until onions become translucent and peppers are a bit softened.
Add the meat and all spices (cumin, paprika, oregano, salt and pepper), mix well and cook until meat is not longer pink.
Add tomatoes and mix well, cook for one more minute then cover the pan and low the heat cooking for about 10 to 15 minutes mixing from time to time.
Adjust with salt and keep cooking until there’s almost not juices left on the pan.
Heat a cast iron skillet or a comal over high heat. Warm up the tortillas from both sides (about 20-30 seconds per side) and wrap them with a kitchen towel to keep them warm and and pliable.
Place two or three tortillas on a plate and spoon some picadillo on the middle. Fold in half, making a little pressure to stick the tortilla with the meat mixture. Repeat until all picadillo is gone.
Heat a generous amount of oil in a frying pan. Fry tacos placing them carefully into the oil and, using a spatula, firmly press down the edges, to prevent them from opening (read notes).
Once picadillo tacos are nicely crispy on both sides, remove from oil and place them onto a plate lined with kitchen paper towels.
Carefully open a taco and garnish with lettuce and tomato slices. Drizzle with cream and with your favorite salsa and finish topping with cheese. Serve immediately.
Is ok of some filling come out from tacos while frying, as long as it's not too much! But if you want to prevent this, you can also use toothsticks and secure the edges of tacos, just remember to discard them before garnishing tacos.
If you using jalapenos, make sure to cut them longwise and discard veins and seeds or picadillo will be too spicy for kids.
