Greek Wedding Soup

I don't know if Greeks really have a wedding soup, it's really just a Greek twist on Italian wedding soup

1 c. brown lentils
1 tsp. Greek seasoning
1/4 tsp. oregano
1 can white beans, rinsed and drained
1 medium onion, chopped
1 - 2 cloves garlic, minced
2 or 3 carrots, sliced into coins
2 stalks celery, sliced
2 Tbsp. lemon juice
6 c. chicken or vegetable stock
1/2 c. orzo or other small pasta
3 handfuls of spinach, chopped fine

Saute onions and garlic until fragrant. Add stock, Greek seasoning, oregano, and lentils and simmer until lentils are tender, about 45 minutes. When the lentils are tender add the white beans, carrots, celery and orzo and simmer until pasta is al dente. Stir in the spinach and lemon juice and continue cooking until both pasta and spinach are cooked.
