Step 1

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)

Step 2

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.
