Spinach Salad

I recently rediscovered this super delicious salad that my mom makes. I made it over Easter weekend up in Utah while visiting the Tucker family and totally loved it! Some people were wanting the recipe so here it is...

2 bunches of spinach washed and stems removed
1 head of red leaf lettuce ripped into bite size pieces
3/4 lb. grated swiss cheese (I substitute mozzarella)
1 lb. bacon fried and crumbled
1 1/2 table spoon poppy seeds
3/4 cup red wine vinegar
1 1/2 cup vegetable oil
1/2 cup white sugar
1 1/2 table spoon white onion minced
1 1/2 teaspoon salt
3/4 teaspoon wet or dry yellow mustard
1 red onion sliced into rings
1 lb. fresh mushrooms (the whiter the better)

To make the dressing:

Combine: sliced mushrooms, minced white onion, sliced red onion rings combine with poppy seeds, red wine vinegar, veg. oil, sugar, salt and mustard. Mix in Ziploc bag and let marinate in for at least 4 hours.

When ready to serve:

Combine spinach, red leaf lettuce pieces, fried and crumbled bacon and cheese with the wet dressing ingredients. Toss and serve.
