2bell peppersI like to use the red and green ones together, sliced into strips
Place the onion and the steak in the bottom of the slow cooker. Mix the salsa, jalapenos, lime juice, taco seasoning, garlic and salt in a small bowl and then pour over the steak and onions in the crockpot. Toss gently to coat. Cook at the lowest setting for 4-8 hours. (see cook's note)
Once the meat is cooked and tender, add the bell peppers and cook another 30-60 minutes, until softened to your preference. Serve with warm tortillas or over rice.
The total cooking time will vary based on your crockpot. I've made this several times and in different crockpots. The cooking time really does vary that much. The first time you make this, you'll want to check the meat after it has cooked a few hours and turn off the heat before it is falling apart.The thickness of the strips of beef will also affect the cooking time. I like to slice ours super thin, maybe 1/8-inch or so, and as a result, the meat will cook through in about 4 hours. If I go much past that, the meat begins to fall apart. Still delicious, but not the strips of steak that you're aiming for here.This recipe does double or triple nicely to feed more people. However, the cooking time will need to be adjusted for that. So, as noted above, check the meat to determine doneness.
