Scale

½ cup soy sauce

⅓ cup vegetable oil

¼ cup lemon juice

1 garlic clove, minced

1 tbsp prepared mustard

1 tbsp Worcestershire sauce

1½ tsp salt (or to taste)

1 tsp coarsely cracked black pepper

1½ lbs lean beef, cubed (1-inch pieces)

16 mushroom caps

2 green bell peppers, chunked

1 red bell pepper, chunked

1 large onion, chunked

8 metal skewers

Whisk all marinade ingredients together and pour into a resealable bag. Add beef and marinate in the fridge for 8 hours.

Add mushrooms to the same bag and marinate another 8 hours.

Preheat grill to high heat. Remove ingredients from marinade and boil remaining marinade for 10 minutes to use for basting.

Thread beef, peppers, mushrooms, and onion onto skewers.

Grill for about 15 minutes, turning often and basting generously, until beef is browned and cooked through.

Serve hot and savor every bite!
