Luau Punch

1 (46 fluid ounce) can pineapple juice

1 (6 ounce) can frozen orange juice concentrate, thawed

2 liters lemon-lime flavored carbonated beverage

In an empty gallon milk jug or pitcher, pour pineapple juice and orange juice concentrate. Shake to mix and pour in the lemon-lime soda. You may need to let the fizz settle and then return to pouring. This will fill up the gallon. Freeze overnight.

Let the punch start to thaw 2 hours before serving. Serve slushy.
