This has been one of our favorite recipes lately. Based on this recipe: http://allrecipes.com/recipe/
3-4 lbs flank steak
1 packet (or 2 cubes) beef bouillon
1 c water
12 oz jar Goya red (tomato based) sofrito
6 oz jar tomato paste (I’ll usually get the garlic or Italian spiced one)
2-3 bay leaves
2 large cloves of garlic, diced small
1 tsp cumin
1 tbsp olive oil
1 tbsp vinegar
Add sofrito, tomato paste, bouillon powder, water, bay leaves, garlic cumin, olive oil, and vinegar to crock pot. Add sriracha to taste.
Brown flank steak on both sides on stove with a little bit of vegetable oil and put into crock pot, covering with sauce as best as possible.
Cover and cook on low heat for 5 – 6 hours
Chop onion and peppers and add to crock pot, cooking for one more hour on low
I suggest serving with yellow rice. It also works well in tacos and sandwiches.
