Makes about 3 cups
12 ounces medium cooked shrimp, peeled and deveined
1 medium white onion, cut into 1/4-inch pieces, rinsed under cold running water and drained
1/4 cup finely chopped recipe ready sun-dried tomatoes
1/4 to 1/3 cup fresh lime juice
Hot green chiles to taste (usually 3 serranos or 1 to 2 jalapenos), stemmed and roughly chopped
1 medium, ripe avocado, pitted, flesh scooped from the skin
1/3 cup (loosely packed) roughly chopped cilantro (thick bottom stems cut off), plus extra for garnish
Mini baked tostadas
In a medium bowl, combine the shrimp, onion, and sun-dried tomato.
Measure the lime juice into a food processor or blender. Cover and turn on. Drop the chiles and when chopped, turn off and scoop in the avocado and cilantro. Process until smooth. Thin to a "creamy dressing" consistency with water, usually 2 to 3 tablespoons. Taste and season with salt, usually about 1 teaspoon. (You will have about 1 1/2 cups.)
Mix the dressing into the shrimp mixture. Cover with plastic wrap directly on the surface of the shrimp and refrigerate. When you're ready to serve, scoop onto the mini tostadas and decorate with cilantro.
