Food before wedding

My bridal party is getting ready at my house before the wedding, they will arrive around 9am, wedding is at 4pm and food will be served around 5:30pm so I want to give everyone a good feed before we go! There will be 6 of us in total but I have 1 vegetarian, 1 with lactose intolerance and 1 very fussy eater (no veg etc) , any suggestions of what to serve that's quick and easy so I'm not spending lots of time cooking
