Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 1/2 cups halved cherry tomatoes with 1 tbsp olive oil and 1/4 tsp salt on a baking sheet. Roast for 15 minutes until tomatoes are soft and slightly caramelized.
  2. Step 2: In a large pot, heat 2 tbsp olive oil over medium heat. Add 1 medium diced yellow onion and sauté for 5 minutes until softened. Stir in 4 minced garlic cloves, 1 1/2 tsp ground cumin, 1 tsp chili powder, 1/2 tsp smoked paprika, and cook for 1 minute until fragrant.
  3. Step 3: Add 1 1/2 cups rinsed quinoa, 1 can (15 oz) drained black beans, 3 cups vegetable broth, 3/4 tsp salt, and 1/2 tsp black pepper. Stir to combine. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes.
  4. Step 4: Remove the lid and gently fold in the roasted cherry tomatoes. Cover again and cook for 5 more minutes until quinoa is tender and liquid is absorbed.
  5. Step 5: Remove from heat and stir in 2 tbsp fresh lime juice and 1/4 cup chopped fresh cilantro. Serve topped with sliced avocado from 1 whole fruit.
