I asked this same question in an earlier post.
The responses were varied.
I have balance bars and power bars which I eat half of prior to my workout since I workout first thing in the morning.
I had previously bought protein powder and when I am home I usually make a shake with nonfat yogurt, nonfat milk and a frozen banana with protein powder and I could mix this with some apple juice if I wanted to make it more of a recovery drink.
Protein wise, I have eggbeater omlet with veggies in the am, either salmon, tuna or chicken at lunch and dinner usually lentils, chickpeas, or chicken with vegetables. I sometimes make salmon cakes to add variety to lunch, but I found this added too many carbs for my phase 1 diet ( probably better for phase 2 where there are more carbs). I also eat yogurt and cottage cheese as snacks.
I do want to try some of the recipes in the p90x book, but I have not had a chance yet.
