Add the olive oil to a sauté and heat over medium. Once the oil is hot, add the onion, carrots, celery, and a pinch of salt. Cook, stirring often, for 5 minutes.
1 tablespoon olive oil, 1 cup chopped onion, 1 cup chopped carrots, 1/2 cup chopped celery
Add the garlic, tomato paste, smoked paprika, cumin, and remaining salt. Stir well to coat the vegetables and cook for 1 minute. If it is sticking, add a splash of water to loosen.
Scoop the vegetable mixture into the crock of a slow cooker. Add the dried beans, vegetable broth, tomatoes, and bay leaves. Stir, then place the lid and set the slow cooker to LOW.
8 ounces dried black eyed peas, 6 cups vegetable stock or broth, 14.5 ounces petite diced tomatoes, 2 bay leaves
Cook for 7-8 hours, until the beans are tender.
In the last 10-15 minutes of cooking, stir in the chopped kale. Cook until the kale is wilted. Stir in black pepper to taste and serve.
2 cups chopped kale, 1/2 teaspoon ground black pepper
Notes
If you are concerned about the tomato acidity affecting the beans, you can wait to add them until the last 30 minutes of cooking.
You can make this recipe using 2 15-ounce cans of beans instead of dried, and simmer on the stove for 20 minutes rather than using the slow cooker. Reduce the broth to 4 cups.
