One Minute Salsa

from Cook's Illustrated (July/August 2002, page 15)

1/2 small jalapeno chile or 1/2 chipotle chile in adobo sauce, minced
1/4 small red onion, peeled and root end removed
1 small garlic clove, minced or pressed
2 tablespoons fresh cilantro leaves
1/4 teaspoon salt
Pinch ground black pepper
2 teaspoons juice from 1 lime
2 small ripe tomatoes (about 3/4 pound), each cored and cut into eighths, or one (14 ounce) can diced tomatoes, drained

Pulse all ingredients except tomatoes in food processor until minced, about five 1-second pulses, scraping sides of bowl as necessary. Add tomatoes and pulse until roughly chopped, about two 1-second pulses.
