From the Tampico website. They recommend you use Tampico Tropical punch, but I suppose you could use any brand. Makes around 40 ounces. I used "frozen concentrate" tropical punch in the ingredients, but using some actual tropical punch would probably be fine.
This came from Firehouse Subs. I like the Hook & Ladder, but it's quite expensive (Around $5.50 for an 8 inch, and $7.50 for a 12 inch). I haven't tried this recipe out, but I brainstormed it up, so tell me if there's any problems. You can change the amount of or remove any ingredient to suit your tastes. Each serving = 1 medium sub. Cooking and prep time are just a guess, but this'll probably take a while.
