Special equipment: about 30 wooden skewers, soaked in water for at least 30 minutes (up to 2 hours)
Preheat the oven to 400 degrees F. Set a roasting rack in a large baking pan.
To make the marinade, pour the teriyaki sauce in a bowl and then throw in the ginger, sugar, crushed red pepper, salt, garlic, green onions and lemon juice. Stir it around and set it aside.
Next, cut the pineapple into chunks by lopping off the top, slicing off the rind, cutting the pineapple into wedges, slicing off the hard inner core and then cutting the slices into chunks. Store half the chunks in the fridge for snacking.
Place a chunk of pineapple on top of a shrimp and then wrap the whole thing in one of the half-slices of bacon. Stick a skewer through the whole thing so that it holds the pineapple, shrimp and bacon securely, and lay it on the rack in the pan. Continue with the remaining ingredients. Brush each skewer generously with some of the marinade.
Roast the skewers for 10 minutes. Remove them from the oven and brush with a second coat of marinade. Return the pan to the oven and roast until the bacon is sizzling and the shrimp is cooked, about 15 minutes.
Serve them hot or at room temperature. Divine!
Try these variations: Cook several pieces together on a metal skewer; substitute large sea scallops for the shrimp; or grill the skewers instead of roasting them. (Just be sure to adequately soak the skewers in water so they won't burn, or use metal skewers.)
