Great with veggies if you are feeling healthy or crisps if you are not. I use both petit pois or garden peas for this depending on whats around. I also use either fresh or frozen, just defrost the frozen ones first.
The best way to serve this is to put the dip into a bowl and have a big board next to it with your veggies on. And have some salt and pepper to hand in case you need it. It's a good sociable way to start a meal.
Remember this will only ever be as good as what you serve with it, for veg I like oval radishes and baby carrots, cos or romaine lettuce, celery etc. Try to get freshest you can, if they still have leafy bits on (carrots radishes etc - leave 'em on, they make great handles)
Edit - I just made this and had no fresh mint. I subbed a generous tsp of mint sauce and forewent the lemon juice and it was great!
