Partially thaw fish and cut into 16 bite size pieces. Sprinkle with lemon juice, seasoning salt, and pepper. Partially cook bacon, drain off grease. Roll each fish piece with a half-slice of bacon, placing bacon on outside and secure with a toothpick. Boil green pepper chunks until partially cooked and drain well. Thread fish, pepper chunks, and pineapple chunks on a skewer, end with a cherry tomato. Broil about 15 minutes, turn and baste frequently with BBQ Sauce.  Grilling is an option.
