Tomato, Peanut Butter and Mayo Sandwich

This is a simple sandwich that I have been eating since I was a little kid. I looked to see if I could find it on Zaar, but was not able to. I just had to post it. I know the ingredients seem like a very unlikely combination, but trust me, these sandwiches are really good! They remind me of summer. Please use fresh, ripe tomatoes! It makes a huge difference! I also reccomend using real mayo, not lite, fat free or miracle whip. This is not a low-fat sandwich, but I figure it is fine on occation...like when the tomatoes are ripe from the garden! Enjoy!
