The summer soup started with a sautee of onions, then summer squash and tomato. I added water, oregano, a few kidney beans, and some balsamic vinegar. If I had a lemon, I think I'd add a splash of lemon juice next time for a more Mediterranean taste.
The fall soup started with a sautee of onions, too, but instead of diced, I cut them in long slivers. (I was going for a French onion soup feel.) Next I added big hunks of portobello. After those looked cooked, I added water, a splash of red wine, oregano, a few bay leaves, a few cloves, and lentils. I let it simmer a long time, so it got stew-like.
The night I made them, we had the fall soup accompanied by a carmelized onion flatbread pizza from our neighbor Eat Local. Very good. Then the next night, we had the summer soup served with Greek roast potatoes (garlic, olive oil, oregano, garbanzos) and pita. Also very good. Win, win.
