There's a sandwich press at my work and I'm trying to think of a way I can meal prep sandwiches for the whole week in one go. I'm thinking freezing them is the best bet, but I want them to be healthy as well and I'm not sure how vegetables will go in the freezer (probably badly).
Ideally I'll make all the sandwiches on Sunday, then put them in the freezer (wrapped in baking paper). Then, I'll take them to work in the morning (straight from the freezer), put them in the fridge when I get to work, and then put them straight in the sandwich press (inside the baking paper). That way I don't have to clean the press.
What would be the best way to incorporate vegetables into the sandwiches (maybe after toasting them)?
