1/2 English cucumber (cut in half lengthwise and seeded)
1 large tomato (quartered and seeded or substitute 2 Roma tomatoes)
1 jalapeño (ribs and seeds removed)
2 cloves garlic (minced or crushed)
2 tablespoons cilantro leaves
1 tablespoon lime juice
1/2 teaspoon kosher salt
Place all ingredients into a food processor and pulse until evenly chopped. Add additional lime juice or salt to taste.
Serve over tacos or with chips for dipping.
Using a food processor makes this recipe very fast, but of course you can dice all ingredients by hand if you prefer.
