Ingredients

- 1 cup dried lentils, rinsed and drained
- 1 medium onion, finely chopped
- 2 carrots, sliced into rounds
- 3 cloves garlic, minced
- 1 can (14.5 oz) diced tomatoes
- 4 cups vegetable broth
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1 teaspoon salt (adjust to taste)
- ½ teaspoon black pepper
- 2 cups fresh spinach leaves
- Juice of half a lemon
Instructions
Begin by gathering all your ingredients and getting your slow cooker preheated on low. Layer in the rinsed lentils at the bottom, followed by the onion, carrots, and garlic. Next, pour in the diced tomatoes along with their juices, and top it all off with the vegetable broth.

Sprinkle the dried oregano, basil, salt, and pepper evenly over the mix. Give everything a gentle stir, cover your slow cooker, and let the soup work its magic on low for about 6 to 8 hours (or high for 4 hours if you’re pressed for time). You’ll know the soup is ready when the lentils are tender and the vegetables are cooked through.
Just before serving, toss in the fresh spinach leaves and stir in the lemon juice for a refreshing, bright finish. Taste and adjust the seasonings if you like a little more zing.
