Well a hippie would substitute tofu. I do a combination of sirloin, ground turkey, and bison. High in protein, low fat. Helps me keep that medical.

Rick, as for taco salad I'd suggest getting some already prepared tortilla bowls - they have them at Kroger in the bread section. Queso fresco makes a nice touch instead of cheddar.

And of course, if you can get Mila Kunis to toss your salad, even better.
