Plants that deer don't eat, as much

First of all, deer absolutely love hostas. If you like watching deer in your backyard, plant a whole bunch of hostas.
But if hungry enough, deer will eat nearly anything growing in your yard. The plants that have the best chance of surviving raids by deer are flowers and plants that have a pungent scent, fuzzy or woody leaves and/or an unpleasant taste.

Vegetables
I have found that deer will eat jalapenos when hungry enough, but that's not their first choice.. They don't usually eat onion, potato, squash and tomato plants or parsley or other herbs.
Their favorites as I know from personal experience, are green beans, Swiss chard, spinach, lettuce, carrots, peas and broccoli.
