Peas? As in peas in a pod, green peas? That sort of peas?
I used to make a salad with peas, cauliflower and onion.
Saute the onion.
Cook the peas and cauliflower (boiling it in water) until just tender. Drain.
Add all the ingredients together and make a dressing with english mustard, vinegar and oil. Season to taste.
I liked adding dill to the mix. Thought it needed a little lift and dill was my herb of choice for this recipe.
