I agree with josmit, tomatoes would be very nice. I halved the recipe and added 2 large pinches of red pepper flakes. I didn't add as much romaine as was stated because I served it with a salad and gralic bread. My husband gave the thumbs up to have again.
This was a little bland for our taste. We loved the idea of it and the wilted lettuce was nice. We decided that chopped tomatoes would be a nice addition. Very, very easy to make!
