A simple but tasty marinade works magic to tenderize these beef and veggie kabobs on the grill.
Prepare marinade. Combine oils, lemon juice, salt, marjoram, oregano, pepper, garlic, minced onion, and parsley in a large bowl or plastic container with a lid. Stir to combine.
Add beef to marinade. Stir til coated. Then add the veggies. Gently toss until well-coated.
Cover, and marinate for at least 4 hours, but preferably overnight. Toss the mixture once or twice.
Place meat and veggies on skewers. You can make them random, or with a pattern.
I like to grill these kabobs outside, but you can also broil them in the oven. Heat grill to at least 350, and turn the kabobs occasionally to desired doneness. For medium, it will take about 15 min. Keep an eye on them!
Remove from grill when done to your liking. Serve with rice and salad.
