The fresh salsa in this easy load-and-go taco recipe is a great way to use spring rhubarb. If you don't have rhubarb, try subbing in fresh tomatillos or red bell pepper for an equally beautiful and delicious taco topper.

  • 2 tablespoons chili powder

  • 1 tablespoon dried oregano

  • 1 tablespoon ground cumin

  • ½ teaspoon garlic powder

  • 1 ½ teaspoons salt, divided

  • 3 pounds beef chuck, trimmed and cut into 1-inch cubes

  • 1 tablespoon avocado oil or grapeseed oil

  • 1 large onion, halved and sliced

  • 1 cup low-sodium beef broth

  • 3 tablespoons tomato paste

  • 1 cup chopped fresh rhubarb

  • 1 teaspoon white sugar

  • ½ cup chopped yellow bell pepper

  • 1-2 jalapeños, seeded if desired, finely chopped

  • ¼ cup finely chopped red onion

  • ¼ cup chopped fresh cilantro

  • 1 tablespoon lime juice

  • 16 corn tortillas

  • Lime wedges for serving


  1. Combine chili powder, oregano, cumin, garlic powder and 1 1/4 teaspoons salt in a small bowl. Sprinkle beef with 2 tablespoons of the mixture.

  2. Heat oil in a large skillet over medium-high heat. Add the beef and cook, stirring occasionally, until browned on all sides, 5 to 6 minutes total. Place onion slices in a 5- to 6-quart slow cooker. Add the beef. Whisk broth and tomato paste into the remaining spice mixture and pour over the beef.

  3. Cover and cook on High for 4 hours or Low for 8 hours. Shred the beef with 2 forks. Stir back into the liquid.

  4. Meanwhile, toss rhubarb and sugar together in a medium bowl. Let sit for 10 minutes. Add bell pepper, jalapeño to taste, red onion, cilantro, lime juice and remaining 1/4 teaspoon salt and stir to combine.

  5. Serve the beef with tortillas, the rhubarb salsa and lime wedges.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
