Tropical style tomato snack

This recipe starts similar to the Italian tomato snack, but the taste is very different and fresh. The mix of ingredients is typical South American, but not very hard to find (the trickiest one was the cheese, but now that I contacted the guys from Queso Blanco Dublin, I have that craving covered).

By the way, when picking an avocado, make sure it's not too firm (that means it's still unripe), not too mushy (too ripe, usable for guacamole, maybe). If you shake it and the stone moves a bit, it's a good sign.

Ingredients (for 15 pieces)

15 crackers (you can use tortillas or nachos for a Mexican touch)

3 tomatoes

150 gr. of grated queso blanco

4 tablespoons of sour cream
1/2 avocado

Directions
Spread the sour cream on the crackers.

Add the tomato (sliced or chopped, as you prefer).

Add a couple of pieces of avocado (if it's very ripe, you can mash it and add it with a piping bag).

Complete with the grated cheese on top of everything. You may add a bit of salt as well.

Serve cold.
