Slightly brown shrimp and remove from heat. Cut shrimp into small pieces and place in a bowl. Add green onions, red pepper, and feta cheese to bowl with shrimp and mix all ingredients together.

Remove from oven and add a scoop of the shrimp mixture into each wonton wrapper. Return to oven for 5-10 minutes or until well heated. Serve warm.
