Ingredients

1 poblano chile 

2 pounds (about 6 medium) green tomatoes, seeded and finely chopped 

1 small or 1/2 large Vidalia or other sweet onion, finely chopped 

1 medium cucumber, peeled, seeded, and finely chopped 

4 scallions, sliced thinly crosswise 

2 tablespoons freshly squeezed lime juice (about 2 limes) 

1 tablespoon extra-virgin olive oil 

1/2 cup finely chopped fresh cilantro 

Coarse salt and freshly ground pepper 

Preparation

Roast chile directly on a gas-stove burner over high heat, or under the broiler, turning as each side blackens. Transfer to a bowl; cover with plastic. Let stand until cool enough to handle. Peel off skin; discard stem and seeds. Finely chop chile, and place in a medium bowl.

Add tomatoes, onion, cucumber, scallions, lime juice, oil, and cilantro. Stir. Season with salt and pepper; let stand 30 minutes. Store in refrigerator up to 3 days.
