Preheat oven to 350F.

Place cheese in circles on a non-stick baking sheet (a silicone baking mat works wonderfully here), approximately 4" in diameter.

This recipe should make 4-6 tostadas, depending on the size Place in oven for 8-12 minutes.

You want it to get crispy in the center, but not so much so that the edges begin to burn.

Remove from oven and allow to cool for 5 minutes.

Top with ingredients of your choice and enjoy!
