Curried Lentils with Sweet Potatoes

This is a great cold weather one-pot-meal we eat pretty regularly these days at our house. You can even substitute carrots for the sweet potatoes or throw in other veggies you "find" in the fridge!
 
Ingredients
1 cup brown or green lentils, washed and picked over
4 cups broth (veggie or chicken)
1 medium onion, chopped
4-5 garlic cloves, chopped
2 medium sweet potatoes, washed and cut into 1/4 inch chunks
2 cups finely chopped mustard greens (or kale or collards or other green)
2-3 t curry powder
1 15oz can diced tomatoes
salt and freshly ground black pepper to taste
chopped fresh cilantro (optional)

Directions

1. Heat 1-2 Tablespoons broth over medium in a soup pot. Saute the onion over medium heat for about 5 minutes.
2. Add garlic, sweet potatoes, and greens. Continue to saute and add curry powder. Mix well.
3. Add lentils, broth, and tomatoes. Bring to a boil, reduce heat to medium low, and simmer uncovered until lentils and sweet potatoes and tender, about 30 minutes.
4. Serve over rice  or other whole grain.(optional--I use brown basmati rice, and it is delicious.)
5. Add salt, pepper, and cilantro to individual servings.
6. Enjoy!
