This fiery salsa makes for a bright addition to tacos, nachos, or simply eaten with your favorite tortilla chips.
In a medium pot, heat vegetable oil over medium. Add onion, garlic, bell pepper, jalapenos; cook, stirring occasionally, until onion is soft, about 4 minutes. Add diced tomatoes, tomato sauce, and white vinegar. Season with salt and bring to a rapid simmer. Cook, stirring occasionally, until vegetables are tender and mixture thickens slightly, about 5 minutes. Season to taste with vinegar and salt.
