Cooked macaroni
Green Onions, green and white ends, sliced or cut with scissors
Hard-boiled eggs, chopped
Green Pepper, cut up
Radishes
Peas
Celery (I use the leafy end) or celery seed
Sweet pickle relish
Mustard (1 or 2 Tbsp, mainly to color dressing and give it a bit of tang)
Kraft Miracle Whip, or a slaw dressing
If desired: drained tuna, diced ham, diced cheese

I cook lots of macaroni to fill my largest bowl. While it's hot I add the other veggies---about 2 green onion stems, 3 hard-boiled eggs, a green pepper, About 4-6 diced radishes, 2 cups peas, 2 stalks celery. Add tuna or ham, and/or cheese, if desired. Mix Add mustard and sweet pickle relish (with juice) to Miracle Whip and mix into the macaroni. Good still warm, or chilled.

Note: I seldom use salt and pepper in my recipes; you may. As with most recipes, adjust the amounts of ingredients to your taste.
