Pineapple Sirloin Kabobs

1 can (8oz) pineapple chunks
1/2 cup water
1/2 cup soy sauce
1 tsp garlic powder
1/2 tsp salt
1/4 tsp ground ginger
1/4 tsp paprika
1 pound boneless beef sirloin steak (cut into 1 inch pieces)
16 medium fresh mushrooms
1 large onion, cut into chunks
1 medium red pepper, cut into 1 inch pieces

Drain pineapple, reserving juice; refrigerate pineapple. In a large resealable bag, combine the water, soy sauce, garlic powder, salt, ginger, paprika, and the reserved pineapple juice; add steak. Seal bag and turn to coat; refrigerate at least 30 min. ( I like to do all day)
Drain and discard marinade. On skewers, alternately thread steak, mushrooms, onion, red pepper and pineapple. Grill.
