It's summer here. DH's vair posh cousin is coming for lunch. I haven't seen her in ages and want to make something lovely for lunch but I'm a bit stumped. I haven't cooked a lunch for friends EVER so my poor sleep deprived baby brain is going 
Any good ideas or recipes?
I'm thinking nibbles to start, a main meal and desert. Something I can prep in advance would be great.
please can you just do all the thinking for me
