Lentil and Tomato Soup

This recipe was found out of necessity. I had run out of easy things to make for dinner and with the next trip to the grocery store several days away I turned to the staples of my cupboard, and searched for a recipe that would use only what I had. This one looked edible and though I lacked several of the ingredients I made it with what I had and it turned out pretty good. I'm assuming it would be much better with the things i didn't have. We'll see :)
