Martha's Split Pea Soup with Ham

1 tablespoon olive oil
1 chopped medium onion
4 carrots, thinly sliced
3 celery stalks, thinly sliced
1 tablespoon dried thyme leaves
Coarse salt and ground pepper
1 can (14.5 ounces) reduced-sodium chicken broth
1 bag (16 ounces) green split peas, picked over and rinsed
Ham bone plus 2 cups reserved ham from the recipe Glazed Ham with Apricot-Mustard Sauce cut into 1/2-inch cubes
2 tablespoons butter
4 slices whole-wheat sandwich bread, crusts removed, cut into 1/4-inch cubes
1 to 2 tablespoons fresh lemon juice

Directions

In a Dutch oven or 5-quart heavy pot with a lid, heat oil over medium. Add onion, carrots, celery, and thyme; season with salt and pepper. Cook until vegetables begin to soften, 5 to 8 minutes.

Add broth, split peas, ham bone, and 5 cups water. Bring to a boil, reduce heat to medium-low, and partially cover; simmer until peas are soft, 30 to 45 minutes.

Meanwhile, make croutons: In a large skillet, melt butter over medium heat. Add bread and cook, tossing occasionally, until browned and crisp, 6 to 8 minutes. Transfer to a paper-towel-lined plate.

Remove and discard bone from soup. Working in batches, puree only 1/2 the soup in a blender (don't overfill); return to pot. Add ham cubes, and simmer until heated through. If necessary, thin with water. Add salt, pepper, and lemon juice to taste. Serve topped with croutons.

I used regular vegetable oil and did not add the lemon juice. This was still extremely good. Glo and Geoff gave it five stars. Oh, and I also used chicken bouillion cubes instead of broth. ~Mom
