Combine all the ingredients except the cheese, seafood and chips. Put it into a squeeze bottle with a large opening at the tip, or a pastry bag.
Set up as many tortilla chips as will fit on a metal pan, preferably one with a rim. (A pizza pan works well.) Squirt about 1/8 teaspoon of the sauce onto each chip. Top with about a tablespoon of seafood. Squirt another teaspoon of the sauce over the seafood. Top with about a teaspoon of the shredded cheese.
Put the pan into the oven at 400 degrees for about two minutes, or until the cheese begins to melt. Remove from the oven and serve immediately, passing the nachos around to your guests.
