Rinse and drain the lentils, checking for any small stones. Dice the onion. Peel and slice the carrots into 1/4-inch rounds. Slice the celery. Mince the garlic (or measure garlic powder). Chop the red bell pepper and dice the potato into bite-sized pieces.
1 1/2 cups dried brown or green lentils, 1 large yellow onion, 3 medium carrots, 3 stalks celery, 3 cloves garlic, 1 red bell pepper, 1 medium russet or Yukon gold potato
Add the lentils, onion, carrots, celery, bell pepper, and potato to the bottom of a 6-quart slow cooker (a 4-quart will be quite full).
1 1/2 cups dried brown or green lentils, 1 large yellow onion, 3 medium carrots, 3 stalks celery, 1 red bell pepper, 1 medium russet or Yukon gold potato
Stir in the garlic, diced tomatoes with their juices, tomato paste, olive oil, smoked paprika, cumin, thyme, oregano, salt, pepper, and bay leaf. Use a spoon or spatula to work the tomato paste through the mixture.
3 cloves garlic, 1 can (14.5 oz) diced tomatoes, 1 can (6 oz) tomato paste, 2 tablespoons olive oil, 2 teaspoons smoked paprika, 1 1/2 teaspoons ground cumin, 1 teaspoon dried thyme, 1 teaspoon dried oregano, 1-1 1/2 teaspoons fine sea salt, 1/2 teaspoon black pepper, 1 bay leaf
Pour in the vegetable broth and water. Stir well, making sure the lentils are submerged. The mixture may look thick, but the vegetables will release more liquid as they cook.
4 cups vegetable broth, 1 cup water
Cover and cook on LOW for 7–8 hours or on HIGH for 3 1/2–4 hours, until the lentils are tender and the potatoes and carrots are soft when pierced with a fork. Check toward the early end of the range if your slow cooker runs hot.
About 15 minutes before serving, stir in the chopped kale or baby spinach. Cover and let the greens wilt and become tender. Turn off the heat and stir in the lemon juice. Taste and adjust salt and pepper as needed.
2 cups fresh kale or baby spinach, 1 tablespoon fresh lemon juice, 1-1 1/2 teaspoons fine sea salt, 1/2 teaspoon black pepper
Ladle the stew into bowls. Serve as a thick stew or over rice, quinoa, gluten free pasta, or a baked potato for a heartier meal. Garnish with fresh herbs and a drizzle of olive oil or spoonful of vegan yogurt if desired.
