Peel and dice sweet potatoes into ½-inch cubes, chop the onion, and heat 2 tablespoons oil in a large skillet over medium-high heat.
Cook sweet potatoes and onion for 8–10 minutes, stirring occasionally, until potatoes start to soften.
Add drained beans, corn, broth, cumin, and chili powder; simmer for 10 minutes until potatoes are tender.
Squeeze lime juice over the skillet, stir, and serve warm with avocado, cilantro, and tortilla chips on the side.
