In a medium/large bowl combine the tomatoes, avocado, red onion, black beans, black eyed peas, corn, pepper, jalapeno, and cilantro. Toss to combine.
In a liquid measuring cup whisk together the olive oil, lime juice, red wine vinegar, sugar, salt, pepper, and garlic powder. Pour the dressing over the diced vegetables and toss to coat. If not eating immediately, cover and store in the fridge. Before serving toss and stir well.
Taste and season with additional salt and pepper. Serve with tortilla chips.
