Back story
MIL is coeliac and thus absolutely has to have GF food - which makes going out for a quick and easy pub hard.
SIL has two DC with SN who get car sick and so can't travel very far in the car.
I suspect SIL would not feel relaxed going somewhere like a pub because not sure that the DC may not have a meltdown - places they know are better.
We never host because we live 100 miles away and it's a long way to come just for lunch.
But I always feel like we are doing things on THEIR terms.
And we can't host as we don't have nearly enough room for everyone (there are 17 of us in total)
If they lived nearer I'd have them all over to have some kind of relaxed and inexpensive chilli. But I can't work out how we can do things in an easier way.
