Ingredients

  • 2 cups dried lentils
  • 4 medium sweet potatoes
  • 2 cups frozen mixed vegetables
  • 1 large onion
  • 4 cloves garlic
  • 2 tbsp olive oil
  • 1 can diced tomatoes (14 oz)
  • 4 cups vegetable broth
  • 2 tsp cumin
  • 1 tsp paprika
  • Salt and pepper to taste
  • 2 cups fresh spinach

Instructions

  1. 1

    Prep your base

    Dice the onion and mince garlic. Cube sweet potatoes into 1-inch pieces. This is your flavor foundation and it takes about 10 minutes.

  2. 2

    Build the flavor

    Heat olive oil in a large pot over medium heat. Sauté onion for 3-4 minutes until translucent, then add garlic and cook 30 seconds more.

  3. 3

    Add the hearty stuff

    Toss in cubed sweet potatoes, lentils, diced tomatoes, and spices. Stir everything together and let those flavors mingle for 2 minutes.

    Simmer to perfection

    Pour in vegetable broth and bring to a boil. Reduce heat to low, cover, and simmer for 20-25 minutes until lentils are tender and sweet potatoes are fork-soft.

  5. 5

    Finish strong

    Stir in frozen vegetables and spinach during the last 5 minutes. The spinach will wilt beautifully and the frozen veggies will heat through perfectly.

Nutrition Note

This recipe delivers complete protein from lentils, complex carbs from sweet potatoes, and plenty of fiber and vitamins from the mixed vegetables—all for about $2.50 per generous serving.

Storage Tips

Store in the fridge for up to 5 days or freeze portions for up to 3 months. It actually tastes better the next day when all the flavors have had time to marry. Reheat with a splash of broth if needed.
