Portable dinners

We are at the start of a long process.
At the moment we are using more fossil fuels than we ever did when living in town. The car, the ride on mower, the quad bike, the chain saw - all use fuel and all are being well used at the moment. This is just for a time while we get everything back under control.
Our current lifestyle does mean due to some child activities we end up needing to stay in town longer during the day. To avoid even later evenings, we are getting good at creating portable dishes, that we can make the night before and then take with us.This also saves on buying takeaways all the time. In the summer we treated it like a picnic.
These are the dishes we have made, taken in the coolie bag and that can be eaten watching sport or waiting for activities to finish.

Picnic rolls - this was in summer, when we just took sliced tomatoes, sliced cheese, sliced cold meat and lettuce, and made them on the sidelines
