I am on desert this year and I am also stuck with a plaster cast on my leg so I have gone with some easy options.

I am doing rainbow jelly frog in a pond, fruit platter and a platter of shortbread, salted caramel fudge and macaroons (the last platter are all bought items).

My sil's all seem happy with the variety yet it is minimal work as I am guessing you already have more than enough on your plate.
