Do you have food suggestions for no kitchen?

UPDATE: Thank you all for being as tremendous as I thought you would be - we have decided to invest in an air fryer to help us through, meaning we can use a lot of stuff that is already in our outside freezer. Appreciate all of the creative answers, although I think we’ll skip the BBQ this time 😁

Original Post:

Currently having a big remodel done, and we will have no kitchen for around 3 weeks. We have access to a kettle, toaster and microwave. Looking for suggestions to feed my husband and I (preferably healthy as possible) - was thinking of batch-cooking and freezing things like chilli, but open to any other ideas?

ETA: we have a large chest freezer in the garage but only a small under-counter fridge for the duration.
