Hello! Looking for suggestions on how to make this more efficient:

When my partner & I travel and visit cities for 1+ days, we like to buy some groceries to make our breakfast and lunch at our airbnb, to take with us while we’re out walking around for the day.

We’ve stored this food in collapsibile silicone containers and it’s worked pretty well, but I wonder if there’s a better way?

If you do this, do you pack your own utensils? A cloth? Do you have a dedicated lunch bag you put in your day pack to avoid leaking? Silicone bags or regular ziploc bags? What’s in your kit?

I’m looking for a lightweight, leak-free and easy to clean system. Let me know your ideas, thank you!
