What do most people usually consider "enough" nuts in a day?

Currently, I'm on a Whole30. I don't have any real grab and go snack options that I can easily get, so so far I've been eating a lot of nuts. Probably too many. Any snack-y ideas for when I want something quick and easy to eat? I get all of my meat and veggies, but it's hard to configure prep and all that with a tiny kitchen and 3 burners between 4 people.

How many servings of nuts would you consider too many per day? And what are some good portable options while on the Whole30?

(God, I miss cheese.)
