Make the Cheese Cups
Preheat your oven to 375°F (190°C).
Line a large baking sheet with parchment paper.
Place the 8 cheese slices on the parchment paper, ensuring they are spaced at least 2 inches apart.
Bake for 5-7 minutes, or until the edges are golden brown and the center is bubbly. Watch them closely to prevent burning.
Remove the baking sheet from the oven and let it cool for about 1-2 minutes, just until the cheese is cool enough to handle but still pliable.
Carefully lift each melted cheese circle with a spatula and drape it over the back of a muffin tin, pressing gently to form a cup shape.
Let the cheese cups cool completely on the muffin tin until they are firm and crispy.
Prepare the Pico de Gallo
While the cheese cups cool, combine the diced tomatoes, red onion, jalapeño, cilantro, and lime juice in a medium bowl.
Season with salt and pepper to taste and mix well.
For best flavor, cover and refrigerate for at least 30 minutes to allow the flavors to meld.
Assemble and Serve
Once ready to serve, carefully remove the crispy cheese cups from the muffin tin.
Fill each cheese cup with a spoonful of the fresh pico de gallo.
Serve immediately and enjoy!
Work quickly when shaping the cheese cups. If they harden too fast, pop them back in the warm oven for 30 seconds to make them pliable again.
