Blanch the tomatoes in boiling water to get the skin off and remove skin. Be careful because the tomatoes will be hot. Cut the tomatoes in half, and remove some of the seeds/liquid and core. Place in blender.
Add red onion, bell peppers, jalapeño ,lime juice, and cilantro to blender and blend on "salsa" setting until you achieve your desired consistency.
Using a spatula, scrap out salsa into a bowl. Add corn, beans, and salt and pepper(to taste).
Serve with tortilla chips, or with tacos, burritos, etc.
