Watermelon and Orzo salad

This came to us with ingredients but no proportions given as we were supposed to assemble to our taste.

About one cup of orzo pasta, cooked and cooled
Watermelon cut into bite-sized pieces.
Arugula or watercress
Italian parsley, chopped
Feta cheese, crumbled

Dressing:
Lemon juice
Minced shallot
Olive oil
Tbsp honey
Tbsp Dijon mustard
Salt and Pepper

We made this and it was GOOD.

(I did not list our proportions of ingredients on purpose. If and when some members make their own salad...and list their proportions...then I will list ours...and perhaps I can learn something).
