Saute the beef with the peppers and onions until the beef is completely browned.
Stir in the cumin, paprika, tomato paste, salt, and chili flakes.
Cook for 5 to 10 minutes, stirring occasionally, until the excess liquid has evaporated.
Take the pan off the heat and mix in the cheese and beans, then let the mixture cool down.
Meanwhile, make the sauce. Heat the oil in a pan and add the onion, peppercorns, salt and jalapeno.
Cook for about 5 minutes or until the onions are translucent, and then add the wine and vinegar and cook until the liquid has evaporated.
Stir in the cream and then let the mixture sit for a while.
Put the pan back over the heat and bring it to an almost-simmer.
Put the cheese in a bowl and pour the hot cream mixture through a sieve over the cheese.
Stir for a few minutes as the cheese melts.
Divide the meat mixture between the tortillas
Then roll the tortilla up like a burrito.
Fry the rolled-up tortillas in a skillet seam-side down until browned all over.
Trim the ends using a serrated knife and then cut in half across the middle and then again, so you end up with 16 pieces.
Discard (or eat!) the trimmed ends and serve with the cheese sauce and some cilantro and/or salsa too if liked.
