DH takes leftovers. And fruit. Occasionally something baked but not often.

Healthy options would be:

Baked chickpeas (I love these!)
Nuts (or pepitas/sunflower seeds if nutfree)
Dried Fruit
Homemade granola
Vegetable patties or slices
Hommus and veggie sticks
Wholegrain crackers
Yoghurt with stewed fruit
There are heaps of recipes for those raw food energy balls
