Anyone have a good recipe for ground beef to go in tacos or burritos?

Picadillos, the usual ground meat fillings, vary quite a bit; they generally contain vinegar and raisins for a sweet sour contrast, and onion and garlic. If you're making a stand alone filling (as opposed to serving with a variety of salsas) You'll need some peppers- Poblanos and Jalapenos are generally available and work well, but any of the Mexican peppers can be used. Spices usually include cumin and Mexican oregano, and some sweet spices such as cinnamon, clove and allspice (in restrained amounts). You should be able to wing it- you're just adding flavorings to ground meat, there's no real structural element and you don't owe anything to "tradition", so use what you like. Hopefully that doesn't include junk like onion and garlic powder, or premixed spice blends. My fillings, not in any tradition I know of, include a lot of onion caramelized along with an assortment of peeled peppers (which I grow-fresh Anchos, New Mexicos, Pasillas etc. plus something hot- jalapenos usually) and cumin, Mexican Oregano and thyme, maybe salt if I'm in a wild mood; a touch of vinegar (sometimes lime juice) and a very unauthentic handful of sweet yellow corn; I mostly skip the sweet spices.

I like this recipe for ground meat in tacos. I substitute ground turkey but the recipe actually calls for ground beef.

Here is a recipe for taco seasoning that I use for tacos, burritos, tostadas and salads. The rest would be just to choose your condiments and or toppings. Avocado, shredded lettuce, cheese, salsa, cilantro etc.
