Amount is all relative to how many mouths you have to feed. I used 6 ears of corn, with the corn taking off the ear after cooking ( boiled method but you could grill it too). 1 lb of green beans, cut and blanched. 2 packages of frozen lima beans cooked, 2 big handfuls of chopped basil.
2 tbsp. white balsamic vinegar
1 tbsp. soy sauce
2 tsp. honey
1 tbsp. dijon mustard
Mix all that together and then slowly whisk in olive oil until the dressing gets thick and tastes right to you. About 1/2 cup of olive oil or less. Sometimes I like the dressing a little more tart and then I use less olive oil.
Make sure all ingredients are at room temperature before mixing. Tastes just as good the next day!
