Ravioli.
The carbs + protein always seem to stick around for a while.
Easy fast!
I usually try to eat like 3 sheets of "machine matzah" the night before a fast. It sits in your stomach like a brick the whole next day!
Last night I went to Smokey Joe's in Teaneck with my wife, my cousin, and his wife, so I didn't eat matzah... I had prime rib, potato salad, and chili. And lots of water. When I got home I downed about 48 ounces of Powerade. It was totally worth it, even if the fast won't be as easy. That food was great.
