Slice the flank steak into thin, even strips. Cut the bell peppers and onion into thin slices. Mince the garlic.

Pour the olive oil into the bottom of your slow cooker, then add half of the sliced onions and peppers. Lay the steak strips on top, then add the remaining peppers and onions. Sprinkle the chili powder, cumin, smoked paprika, oregano, salt, black pepper, and crushed red pepper flakes. Add the minced garlic, drained diced tomatoes, and beef broth. Squeeze the lime juice over everything.
Step 3: Cook Low and Slow
Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the steak is fork-tender and the vegetables are perfectly soft. Stir once halfway through for even flavor.
