Dips are really easy to make yourself.
Dd's favourite I make is sour cream, garlic salt parsley and basil.
Beetroot and coriander is nice and easy.
Home made houmous takes mins.
Cream cheese, garlic, parsley, basil and oregano
Cream cheese with spices can be nice.
Home made salsa - cheat with tinned toms or Blanche and peel your own. Add chilli peppers, coriander, black pepper, garlic, sea salt, parsley and lemon juice.
Regarding hard cheeses remember not all are veggie and some people can even be allergic to rennet.
Cheese straws glazed with Marmite are lush.
You could even go 'kitsch retro' with vol au vents filled with veggie pâté, egg Mayo, mushroom and cream cheese etc.
Have fun
