Doesn't sound very fast. Also sounds serious. Manchego y Chorizo Tapa con Membrillo Does it sound any simpler in Spanish?
Let's just call it good. This crunchy, little toast is the perfect pile of salty, meaty and sweet with a jigger of freshness by way of mint leaves. The most difficult, and okay, a bit spendy, part of this tapa, is the tracking down of the fine, Spanish ingredients--Manchego, Chorizo and Membrillo (quince paste- a spicy, sweet, firm jam that is a traditional accompaniment to cheese-- oh, and if you don't know what a quince is....). A cheese boutique, a Spanish specialty shop or a Fancy Food Mega Store should carry everything needed. If you live where there are no such markets, consider some click-and-spend shopping with La Espanola. (While there, order some cantimpalitos, Spanish cocktail sausages, for your next soiree--they're awesome.)
So, in 60 seconds, you spread a layer of membrillo on a toast or cracker. Arrange a few mint leaves over the membrillo, top with a couple of thin slices of chorizo (I like Espanola's Cantimpal or Fra' Mani's Chorizo) and top with a piece of Manchego. Repeat until you are satisfied.
