My friend, Johanna, made the wonderful kabobs. Sooo yummy!
1/4 cup balsamic vinegar
1 T canola oil
2 T Worcestershire sauce
ground black pepper to taste
1 lb very lean beef tenderloin or top sirloin
2 small onions - peeled and quartered
1 lg. bell pepper - cut into 12 pieces
8 whole cherry tomatoes or 4 plum tomatoes, halved
4 tsp horseradish sauce
**You can use other veggies like whole mushrooms, chunks of zucchini, or yellow summer squash.
In a bowl, combine vinegar, oil, Worcestershire sauce, and pepper. Mix well. Cut meat into 16 cubes. Put meat in flat dish in one layer and cover with vinegar mixture. Marinate for a minimum of 30 minutes. (Best when left all day or even overnight.)
Divide all ingredients out evenly between 4 skewers. On a hot grill cook for 12 minutes turning twice. Serve with teaspoon of horseradish sauce of each plate.
