Spinach Muffins

Add to my passover recipe box

2    medium onions, chopped
½   cup celery, chopped
1-½ cups grated carrots
6    tablespoons margarine or 3-4 tablespoons vegetable oil
1    10-ounce box frozen spinach, defrosted and drain well
3    eggs, beaten
¾   cup matzah meal
1-½ teaspoons salt
¼   teaspoon pepper

Preheat oven to 350 degrees and grease a 12-cup muffin tin. In a skillet over medium heat, sauté onions, celery, and carrots in margarine until almost tender.  Add spinach during last two minutes of cooking. Transfer to a bowl, add eggs, matzah meal, and seasonings.  Spoon into the muffin tins.  Bake for 45 minutes.  If planning to reheat before serving, decrease baking time by 5 minutes.
