In a pan over medium heat, caramelize onion in olive oil to your preference and sprinkle with salt.
Place one phyllo sheet on a baking sheet and brush with melted butter.
Repeat until you are done with all the sheets and you’ve got the pizza base that you like.
Spread sauce evenly over.
Arrange onion,shrimp and peppers on top.
Bake for 15-20 minutes until golden brown.
Cut and serve with some salad.
* Use more for a thicker crust. ** Some people like using olive oil others like spraying cooking oil on their phyllo, personally I like and recommend butter as stated in the post above. *** Feel free to play a little with other sauces that you love.
