  • 1 ½ pounds skirt steak
  • 2 bell peppers (I used one red and one yellow)
  • ½ large red onion
  • 8 oz sliced baby portobello mushrooms
  • 2 tablespoons olive oil
  • Juice of one lime
  • 1 tablespoon honey
  • 1 teaspoon chili powder
  • 1 teaspoon cumin
  • ½ teaspoon garlic powder
  • ½ teaspoon dried cilantro
  • ½ teaspoon sea salt
  • ¼ teaspoon pepper
  • Flour tortillas
  • Sour cream, cheese for serving (optional)


  • Place skirt steak in bottom of slow cooker
  • Remove ribs and seeds from peppers and slice then add to slow cooker on top of steak
  • Peel onion and slice into petals and add to slow cooker
  • Add pre-sliced mushrooms on top
  • Whisk together all remaining ingredients and pour over meat and veggies
  • Cover and cook on high for 3-4 hours or low for 6-8
  • Remove and slice steak and remove veggies from slow cooker (you won't want all the sauce as they would be soggy)
  • Serve with tortillas, sour cream, cheese or as desired
  • I cooked these on high in my 4-quart slow cooker for 8 hours


Need a cool lime squeezer? Simple is best! Mine is yellow but pretty much like this one and works great and is easy to clean!
