In a medium bowl, mix soy sauce, light brown sugar,
distilled white
vinegar, garlic powder, seasoning salt, garlic
pepper seasoning and
lemon-lime flavored carbonated beverage. Place
beef sirloin steak in
a large ziplock bag. Cover with the soy sauce mixture
and seal.
Marinate in the refrigerator 8 hours, or overnight.
Preheat an outdoor grill for high heat and lightly
oil grate. Place
green bell peppers in a medium saucepan with enough
water to cover.
Bring to a boil and cook approximately 1 minute.
On wooden or metal skewers, alternately place
steak, parboiled green
peppers, mushrooms, cherry tomatoes and pineapple.
Basting frequently
with remaining marinade mixture, cook on the prepared
grill 10 to 15
minutes, or to desired doneness.
