Without naming names, because "those" vegetable chips are pretty darn good, I will say you can make better ones yourself. All you need is some masterful knife skills or a mandoline. I love when I recreate something at home that I overpaid for at a store. It makes me feel so accomplished in a geeky, cheap kind of way. Or should I say frugal. I have done these kind of chips with sweet potato, potato and carrot. All very yuumy.
When you eat a lot of beets, remember, certain bodily functions will produce red results. Don't be alarmed and call your doctor right away. It should subside in 24 hours or so.
For beets- here is the process:
5 medium beets
Cut tops off of the beets and place in a saucepan, covering with water. Bring to a boil and cook until beets become tender. Remove from water, let cool, enough to handle. Peel the skin off of the beet. Slice thinkly or slice with a mandoline. Place ona sprayed baking sheet, with none overlapping. Bake in a 425F oven until chips become somewhat golden or darkened. Remove and let cool.
Alternately, you can do this in a microwave in small batches as well. Heating and checking frequently until the chips become browned. I have heard that heating things int he microwave causes a loss of nutrients.
