This type of salsa, made with chopped tomatoes, bell peppers, and herbs, is a classic salsa fresca—which means it is not cooked. Serve this with just about any meat or poultry. We especially like it on burgers.
You can use frozen corn kernels, cooked and cooled. For better flavor, use leftover boiled summer corn, or better yet, grill a few ears over hot coals or roast them in a very hot oven (400?F) until the husks blacken, which will take about 15 minutes and require turning several times. Let the corn cool and then slice the kernels from the cobs.
