This is my favourite beef taco recipe. It can be made in the slow cooker or oven, either way it is delicious.
Preheat oven to 300 F. If using a slow cooker spray inner lining with nonstick cooking spray.
In a large bowl, toss beef with chili powder, mix well.
Heat oil in a large oven proof dish or, if using a slow cooker in a medium size skillet.
Add onions and cook 3-5 minutes or until tender but not browned.
Add tomato paste, mix well. Cook an additional 1 minute. Add beef. Cook until all sides of beef are browned but beef is not completely cooked. Add in salsa and chicken broth. Bring to a boil.
If using an oven proof dish, cover and place in oven for 4 hours or until beef is tender. If using a slow cooker, transfer beef mixture into slow cooker and cook on low for 6 hours or until beef is tender.
Make sure most of beef is covered by liquid while cooking.
If needed, and according to your preference, shred beef with two forks after it is cooked.
Place 2 heaping tablespoons of beef mixture onto each corn tortilla. Top with 2 tsp guacamole, chopped cilantro and sliced radishes.
