I would glug the nastiest tasting (and texture!) concoction of cranberry juice and berry flavored rice protein powder. I was vegetarian for three years and felt it was the only way I could get enough protein in my diet.
In my early teens my mom put me on weight watchers and I’d eat plain yogourt (healthy!) mixed with sugar free aspartame-crap vanilla pudding mix (not so healthy!) and let it “set” overnight. I’d eat it topped with canned unsweetened pineapple chunks. That one was actually quite tasty… but strange too…
