All absolutely amazing!
I am wondering about eggs plus eggs on day 2. Consider either baked omelette or frittata for breakfast.
I saw this the other day, I wonder if it would be easy to make ahead for lunch on day 2. https://ottolenghi.co.uk/pages/recipes/portobello-steaks-butter-bean-mash
Plus you could use anything you have left over from the other meals as accompaniments - all the things you are having with wraps, for example. Or a salad as accompaniment. Some left over wraps on the side, cut in half, maybe crisped in the oven.
Gee they are going to eat well. Wish I was going to be there 😄
