Beans sautéed with tomato, onion, and chile in a quick, flavorful stir-fry style. This vegetarian, protein-rich family side is a fast, healthy way to serve beans any night.
Heat 2 tbsp olive oil in a large skillet over medium heat until shimmering but not smoking.
Add the sliced onion and jalapeño; sauté for 3–4 minutes until onion is translucent and jalapeño is softened.
Stir in minced garlic and cumin; cook for 1 minute, stirring constantly to release aromas but not burn the garlic.
Add diced tomato and cook 3–4 more minutes, stirring frequently, until the tomato breaks down and ingredients are saucy.
Fold in the cooked pinto beans, salt, and black pepper; reduce heat to low, covering to warm everything for 8–10 minutes, stirring once or twice to avoid sticking.
Taste for seasoning, stir in chopped cilantro just before serving, and serve immediately as a protein-rich side or filling.
