Disney, it depends on the ingredients. Lots of veggies, it can be both a veggies and a protein.
Sadie, Turkey burgers can be good, too, but they don't have the veggie component. Also, they do have the risk of handling raw poultry--that's not a huge risk, and it's one that many of us deal with often, but when you're in a hurry, it's nice to be able to pull out a frozen veggie burger and not have to worry about cleaning surfaces and cutlery and your hands, you know?
I love Morningstar's Tomato Basil Pizza Burgers. I only eat them in Phase 2, but I have one for breakfast once a week with a slice of 2% cheese and a pepper with hummus. Great breakfast, and very tasty. These things smell SO good that everyone in my building comes in the office when I make one and wants to know who's having pizza.
I like Gardenburger's Wild Rice and Portobella burgers. They are tasty.
Just watch ingredients and make sure that they are good for the phase you are on. Okay?
