1 cup canned crushed tomatoes
1/2 cup roasted red peppers packed in water, drained and chopped
1/4 cup canned diced green chiles
1 tbsp taco seasoning mix
1/2 tbsp garlic powder
1/4 tsp red pepper flakes, or more to taste
1/8 tsp. black pepper, or more to taste
1 1/2 lbs raw top sirloin beef, trimmed of excess fat
In a crock-pot, mix all ingredients except beef. Add beef and stir to coat.
Cover and cook on high for 4 hours or on low for 8 hours, until beef is fully cooked and tender.
Transfer beef to a large bowl. Shred with two forks – one to hold the beef in place and the other to scrape across and shred it.
Return the shredded beef to the crock pot and mix well. Enjoy!
