Equipment

Ingredients

1 yellow onion sliced
1 red bell pepper sliced
1 yellow bell pepper sliced
1 green bell pepper sliced
1 ½ pounds flank steak
1 teaspoon chili powder
1 teaspoon cumin
1 teaspoon paprika
½ teaspoon salt
½ teaspoon oregano
1 teaspoon black pepper
10.5 ounces diced tomatoes with green chillies drained
¼ cup chipotle peppers in adobo sauce chopped (Optional, leave out if you don't like it spicy)
3 teaspoons garlic minced
2 limes juiced

Instructions

Add onions and bell peppers to the bottom of a 6-quart slow cooker.
Place the flank steak on the vegetables and season with chili powder, cumin, paprika, salt, oregano and black pepper.
Top with diced tomatoes with green chillies, chipotle peppers in adobo sauce, garlic, and lime juice.
Cover and cook on low for 7-8 hours or high for 3-4 hours.
Remove the steak and slice against the grain. Add it back into the slow cooker and mix into juices and veggies.
Serve on tortillas with your favorite toppings and enjoy!

Notes

Give the flank steak time to rest for a few minutes after cooking for a more tender and juicy steak. Resting allows the juices to evenly redistribute through the meat and gives the muscle fibers of the meat time to relax.
Slice the meat perpendicularly across the visible muscle fibers, also known as “the grain” to make the flank steak strips less chewy.
Slice the flank steak into thin strips that are less than an inch thick so they are easier to chew.
