Can't have butternut squash or goats cheese as I'm doing a butternut squash, sweet potato and goats cheese pie.
The rest of us are all fairly unfussy omnivores, but one guest is allergic to peppers and anything pepper related so can't use any of these. The DC won't reliably eat any vegetable so I need a non vegetable component to distract them with so the rest of us can eat.
We are a family with several veggies. I always make (a fortnight or so in advance and freeze it) watercress soup, and just give everyone a very small cupful as a starter (old-fashioned dinner coffee cups). A blob of sour cream and a few chopped chives on top. To my surprise even my teenage DS liked this when I first made this and now its become our traditional starter. Very easy.
Why not bake a Camembert or two and serve with crudités? Carrots, sliced peppers, cucumber etc., nice and fresh in advance of a heavy main course. It's what we're having. Or same idea but with hummus and tzatziki. Keep it simple.
