I got this recipe from my mom in law. It is one of my favorite summertime recipes.
2 crowns of broccoli, coarsely chopped
1/2 red onion, coarsely chopped
1/4 to 1/2 cup shelled sunflower seeds
shredded mozzarella cheese to taste
3/4 cups mayonnaise (not miracle whip)
1/8-1/4 cup vinegar (i prefer apple cider, but white works ok, too)
1-3 tablespoons of white sugar
celery seed to taste
Toss dressing and salad together. It is best chilled for a little before you eat it. This recipe serves about 4-5 people.
