I'm about 90% vegan. On the weekends it's hard for me to eat healthy, so my 'treat', rather than something carb-heavy or sugary is fish... LOVE love shellfish. I might have it once a week or so. And occasionally I'll have eggs. but mostly I eat fruits, veggies, legumes, some soy, and vegan healthy fats.
I used to be a junk food vegan, buying all the frozen goodies at WF, like 'vegan pizza bites' and 'mac and chreese', and Tofutti. Omg, ok... even my carnivore DBF LOVES Tofutti.
