Preheat oven to 350F (180C).

Place bread shells, cup sides up, on 2 baking sheets.

Prepare the peanut sauce: Combine water, soy sauce, cider vinegar, and sugar.

Add the mixture to peanut butter and rice vinegar, mixing well to form the sauce.

Spread the peanut sauce equally over the cups in the bread shells.

Scatter bean sprouts equally on crusts, then sprinkle with shredded Monterey Jack cheese.

Bake in the preheated oven until the cheese has melted and begins to brown, approximately 12 to 15 minutes.

Place pizzas on dinner plates.

Top each pizza equally with shrimp and chopped scallions.

Add chilies to taste (optional).

Serve immediately and enjoy.
