Spicy Lentil + Vegetable Soup

So, are you thinking I should just change the blog name to Soups and Sweets?  Or just Soups and Soups?  That would be a little more accurate, wouldn't it?  What can I say?  We make a big pot of soup every Sunday to eat throughout the week and they're too good not to share.  So here's one more:

Makes about 8 servings.

Spicy Lentil + Vegetable Soup

2 tablespoons olive oil

1 yellow onion, finely diced

3 cloves garlic, minced

2 carrots, peeled, diced

2 celery stalks, diced

1 cup french green lentils

1 14 oz tin diced tomatoes

1 bay leaf

about 2" x 2" piece parmesan rind

2 teaspoons ground cumin

1 1/2 teaspoon ground black pepper

1 teaspoon paprika

1 teaspoon chile powder

1 teaspoon fresh thyme leaves

1/4 teaspoon red chile flakes (omit if you prefer low spice)

6 cups chicken or vegetable stock

8 oz cremini mushrooms, sliced

4 cups chopped collard greens, stems discarded

salt, to taste

juice of half a lemon

In a large pot, over low heat, sweat onions and garlic over low heat until soft and sticky, about 10 minutes.  Raise heat to medium.  Add carrots, celery, lentils, tomatoes, bay leaf, parmesan rind, cumin, pepper, chile powder, thyme leaves and chile flakes.  Give it a good stir and cook for 2 minutes.  Add stock.  Bring to a boil.  Add mushrooms and reduce to a simmer.  Simmer until lentils are tender, about 30 minutes.  Skim off and discard any foam that occurs on the surface.  Stir in collard greens, season with salt and lemon juice.  Remove parmesan rind and bay leaf before serving.
