I have an undetermined number of people coming for lunch on Sunday (between 4-15 of us, unknown until the day...).
I need a proper main meal, that I can prep in advance and leave in the oven on a timer, while I'm at church in the morning.
I'm thinking pasta bake, as every possible attendee will eat pasta, and leftovers can be frozen (I know the texture isn't always great, but on this occasion I think it may be necessary).
I need to make two different trays due to oven space. I know tuna isn't popular with my visitors, and I'm not keen on white sauce, so would rather avoid being left with lots of that. I'm thinking a tomato-based one, but would love inspiration for the second tray.
TIA
(Edit for spelling)
