Grilled Shrimp Tostadas with Avocado Crema and Pickled Onions is one of our favorite summertime dishes. It blends a lot of elements that we absolutely love – the sweet and creamy richness of the avocado crema, the luxurious mouthfeel and deep flavor of the shrimp, the crunch of the tostada, and the tangy hit of vinegar from the pickled onions.
We usually marinate the shrimp and make the pickled onions the night before, so we can just toss the shrimp on the grill, blend up the crema, and assemble the tostadas for an easy weeknight meal.
The avocado crema has a smooth, beautiful texture that is the perfect vehicle for the bold-flavored shrimp. The chilis in this dish are relatively low in terms of heat and intensity – this isn’t a “hot” dish.
