As the title says, i think samiches and Pickles should be introduced.
We have vinegar and cucumbers (the method of pickling would be left up to Devs)
We have various meats from tuna, pork, beef etc.
We have cheese and bread
we have olives and lettuce
I think having a series of sandwiches would be a great idea.
maybe introduce tomatoes for ketchup and....for tomato slices
mustard seeds would be cool too
maybe add mayo?
i dunno, i feel that bread could have so many more uses than it does now
