It’s Friday, time to share one of my favorite soups with you, one that I have had made over the years, even before I became a strictly whole food, no oil, plant based eater. It is a Hearty Tomato Lentil Soup that just happened to fit into eating plant based.

The original recipe called for oil, but I omit it and can’t taste any difference.

On the winter nights when my husband eats plant based with me, we serve it up on a tray with a glass of red wine and enjoy a cozy dinner while watching a movie.

The recipe has pasta in it. When I want something less calorie dense, I make it without the pasta and it is still delicious.
