Total Time: 27 minutes
Servings: 8

INGREDIENTS:

• 1.5 lb beef tri-tip
• 3 bell peppers (red, yellow green)
• 1 large red or yellow onion
• 16 small mushrooms (about 1-1.5″ in size)

Marinade:

• 1 tsp minced garlic (or 2 large garlic cloves – minced)
• 1 tsp onion powder (or sub with garlic powder)
• 2 1/2 tbsp soy sauce (I use low sodium)
• 2 tbsp Worcestershire sauce
• 2 tbsp balsamic vinegar
• 1 tbsp vegetable oil (or other neutral flavoured oil)
• 1/4 tsp black pepper

DIRECTIONS:

• Cut the beef into 1.5″ wide cubes.
• Mix Marinade in a bowl. Add beef. Marinate for 1 – 24 hours, minimum 20 minutes.
• Cut peppers and onion into 1.5″ wide squares.
• Thread beef (reserve Marinade), vegetables and mushrooms on each skewer. I use 2 pieces of vegetables between each piece of beef. Thread loosely – don’t smush together tightly (helps even cooking).
• Brush kebabs lightly with Reserved Marinade (including vegetables), then drizzle with olive oil.
• Heat BBQ or large skillet over high heat. Add 1 tbsp oil, then when smoking, cook kebabs in batches for 3 minutes on each side until slightly charred (4 sides = 12 minutes in total), basting with Reserved Marinade as you go.
• Transfer to plate, cover loosely with foil and rest for 3 minutes before serving. Garnish with parsley if desired.

NOTES:

• You want the meat to be slightly charred around the edges
