i love lentil soup, try this soup similar to dal :
1 cup lentils (rinsed and sorted, i sometimes use yellow or red lentils)
3 cups broth
1 sliced onion
2 sliced carrots
2 cloves chopped garlic
1 cut potato
1 rib of celery
1 chili pepper (if you want)
spices:
turmeric, cumin, coriander, salt
saute onions in a bit of oil, add the spices, add carrots. after a few minutes and onions have cooked, add garlic. if you have some white wine, up the heat and add about 1/4 cup, cook off alcohol. add broth and the lentils, simmer covered on low heat for about 20 min, then add the rest of the veggies and simmer for another 20 min.
