Mexican can mean so many (delicious) things!
Besides tacos and burritos, another good one is flautas. I just use leftover pot roast, or if you want to start from scratch, put a small beef roast (like a chuck or something not expensive) into the crock pot (8 hours on low, or 3-4 hours on high), along with some minced garlic (or jarred powdered garlic), chopped onion, an 8 oz. can of Ortega diced chiles (or more, if you'd like), a can of diced jalepenos (if you like 'em), some beef broth (I recommend Wolfgang Puck's - it's good and you can pronounce everything in the ingredient listing), a squeeze of lime juice, a shake of salt and pepper, some cumin seasoning and maybe a handful of chopped cilantro. (It's all to taste, and there's no wrong way to do it)
Then, once the meat's done, put it on a large platter & shred it by using two forks.
At this point, you can refrigerate it, in it's juices, if you want to make the meal the next day.
Next step: lay out about a half dozen paper towels, stacked, on top of a brown paper bag or a piece of foil. This will keep your kitchen counter clean. Preheat the oven to 375.
In a frying pan, heat up a bit of canola oil on a med-high setting on the stove(if you have plain vegetable oil, that's fine too). Carefully, place one flour tortilla in the oil. Wait about 20-30 seconds and then flip it over with tongs (don't use a fork - you'll make a hole) After another 30-40 seconds, take it out and lay it on the paper towels.
Put about 3 Tbsp. worth of the meat mixture in a line down the middle. Roll the tortilla but don't tuck in the ends. It should look like a flute (thus, the name "flauta"). Use a toothpick to keep the flute closed at the seam - like an in and out of a stitch.
Lay it, seam side down on a cookie sheet. (foil lined if you don't want a lot of clean up). Do this till you've exhausted your supply of tortillas. Bake till they're golden and crispy without being burnt.
Serve by dipping in a good guacamole -
easiest one (and my personal fav):
mash together an avocado with a squeeze of lemon juice (about 2 tsp or so), a small shake of salt, pepper if you want, and a few shakes of tapatio or tabasco.
