Pesto dressed leafy greens

Do you know those half empty jars of pesto sitting in your fridge, that you once opened excitedly when home alone. They stay there forever. Unless, like today, you use them up. With, e. g.:

Some simple green lettuce
Parsley and
Spring onion

Add a bit of water/veggie broth to your (in this case plain green) jarred pesto
some lemon or orange juice
a little honey
a little soy
a little olive oil, maybe
even a little white balsamico
Salt & pepper to taste.

Shake well and add to lettuces just before serving to prevent soggyness.
