For a milder salsa, remove the seeds and membranes from the jalapeno pepper before roasting. Roasting the vegetables is key to developing the rich, smoky flavor of this salsa. Don't be afraid to let them get nicely charred! If you don't have a broiler, you can roast the vegetables in a 400°F (200°C) oven for about 30-40 minutes, or until softened and slightly browned. Adjust the amount of salt, pepper, and lime juice to your taste.
