Single person here, FIRE and cooking only for myself at the moment. With lunch, I routinely have 12 pieces of cut up fresh vegetables. I know what I like, and it doesn't go to waste: carrots, peppers, cucumbers, mushrooms, olives. (Celery tends to stick in my teeth, and also is too hard to use up.) For supper, I always have a side serving of frozen vegetables: usually broccoli, mixed vegetables, Brussels sprouts, cauliflower, or anything else that may be available at Aldi, where I do most of my grocery shopping. I keep a few canned vegetables in the cupboard just for, hey, whatever...or maybe for power outages. Prices at Aldi are cheap, and I make sure I eat everything up, so I don't worry about the cost...and figure it's healthy, anyway.
