at my regular, non-hfs grocery store, i often buy the following products:
fresh fruits and veggies to last a week or so. then, i buy frozen veggies and fruits to supplement throughout the rest of the week--particularly toward the end as we have finished the fresh fruits and veggies.
i often buy both canned and dry beans. i sprout the dry beans and cook them throughout the week, and then i often use the canned beans if i want to make something quick and i haven't sprouted yet. So, on busier weeks, i'll buy more canned beans, and i'll use them if i havent' sprouted and i want to have some bean-related soup or chili.
i buy the following kinds of grains: boxed quinoa (much more expensive at this store than the HFS), brown rice, polenta mix (which is basicly rough corn flour), and sprouted alvarado street bread.
i also buy nuts, nut butters (if they're all natural) and some all fruit (no sugar) jellies/perserves/jams.
finally, i'll buy soy milk, tofu and tempeh. (i no longer consume soy products on a regular basis, but as a vegan, i ate tofu a few times a week and consumed soy milk every day). i prefer eden soy extra because it is the most fortified soy milk available, with the least sugar and most protien as well. it's just high quality (and more expensive).
i tend not to consume prepared, vegetarian meat analogues. but, amys, boca and garden are good brands, but read the labels. some contain cheese or eggs, so be mindful.
that's basicly it. my favorite things are raw foods, so i tend to eat a lot of fruit, veggies, nuts, and seeds during the day, and then for dinner i like to make some sort of soup with a side dish of some sort of bread or grain and then a vegetable. So, for instance, i might make chili tonite with a side of jalapeno corn bread and a mixed greens salad with tomatoes, avacado and a spicy-citrus cilantro dressing. tomorrow, it will probably morracan carrot soup with quinoa "cous cous" and cucumber-tomato salad, or hummus and whole grain pitas instead of quinoa. so, there you go. pretty easy stuff.
