  • 2 tablespoons extra-virgin olive oil

  • 1 large red onion, finely chopped

  • 4 garlic cloves, finely grated

  • 1 tablespoon ground cumin

  • 1 (450g) package dried Central American red beans

  • 120ml red quinoa, rinsed

  • 1 tablespoon sauce from a can of chipotles in adobo

  • Lime wedges, sliced avocado, soured cream, chopped coriander, crumbled queso fresco or shredded cheddar or Monterey Jack, hot sauce, and/or tortilla strips (for serving)

Heat oil in an Instant Pot or other electric pressure cooker on the Sauté setting. Add onion and cook, stirring occasionally, until beginning to turn golden brown around the edges, 6–8 minutes.

Do Ahead: Soup can be made 2 days ahead. Let cool, then cover and chill. Soup will thicken; add up to 240ml water before reheating over medium-low.
