This marinated beef fillet roll
is really easy to make, can be prepared in advance and does not make heaps of dishes. Serve with simple vegetables steamed or roasted.
Depending on how dedicated you are, I find a simple fruit crumble is usually well received, can also be prepared in advance and is very affordable.
I do equal parts flour and sugar, add enough butter so when I rub them all together it looks like bread crumbs and then mixed spice. Add the crumble on top of fruit sprinkled with some sugar and spice and bake at 180 for 40 mins or so.
