I'm in more of a maintenance mode, and when strawberries come in season here, I was thinking of trying an angel food cake:

12 egg whites
3/4 c. Splenda
1 t. cream of tartar
1 t vanilla extract
1/2 c. soy flour
1/2 c. rice flour

Totals for whole cake (less splenda): 676 cal
Fat: 11 99 15%
Carbs: 80 289 45% Fiber: 8 0 0%
Protein: 63 253 40%

Do all of you bakers out there think that would work? I'm allergic to wheat, but I think the rice flour will be okay for me and would certainly make it lighter than entirely soy (or garbanzo) flour.
