And just FYI, the portion in the bowl below may look a little small (at least compared to some of the other portions I've pictured), this was actually my second bowl of it last night... I forgot to take a picture of the first.
1 cup lentils
6 cups water or broth*
1/2 c. chopped onion
1/2 c. chopped celery (I often use a little extra)
1/2 c. chopped carrots (ditto)
3 cloves garlic, minced
2-3 diced tomatoes or one (14.5 oz.) can diced tomatoes
1 tsp. oregano
1 tsp. basil
salt & pepper to taste*
Combine all ingredients in a large saucepan. Bring to a boil. Let simmer, covered, for one hour or until lentils are soft.
*I normally use half water, half broth, and add 1 tsp. salt. Pepper is easier to do "to taste," I think, and less of a problem if you guess wrong. :-)
