Use spice paste for your shrimp po boys, to spice up a mayo in a chicken or tuna salad, on grilled butterflied jumbo shrimp, add to chilis or soups, or to rub on chicken breasts, chops or steaks before broiling or grilling them.

1/4 cup coarsely chopped onion
1 clove garlic, peeled
1 tablespoon roughly chopped fresh flat-leaf parsley leaves
1/2 jalapeño pepper, seeded
1/4 teaspoon ground cayenne pepper
1/4 teaspoon dried thyme
1/4 teaspoon paprika
Kosher or coarse salt and freshly ground black pepper, to taste

Place the onion, garlic, parsley, jalapeño, cayenne, thyme, paprika, and salt and pepper in a food processor and process until the spice paste is well blended, scraping down the sides of the bowl at least once. Transfer the paste to a small plastic container. Cover and refrigerate until ready to use. You can add a little vegetable oil to the paste if you need it a little thinner.
