Honestly, I'd have to get all three! Sounds like a great combination.
For non-cooking, I'll mash up an avocado and mix it with chopped bacon, maybe a little mayo, maybe even chopped hardboiled egg. Apple slices make good dippers, too.
Deviled eggs are handy to keep in the fridge.
Cold sliced steak with mustard.
Thin-sliced ham rolled around a pickle.
Frozen berries mixed with coconut milk/cinnamon/vanilla makes a great summer snack.
Your folks don't have a microwave?
