Spinach Salad

I made this salad over the weekend for a family get together. I came home with an empty bowl and many requests for the recipe. It's quick and easy using many ingredients that are on hand already. 1 bundle of spinach
1 head of lettuce (or all spinach)
1 purple onion, thinly sliced (I used half an onion and it was plenty)
mushrooms, sliced
1 cup cottage cheese or feta
3/4 cup grated Swiss cheese
1/2 lb cooked and crumbled bacon*
optional: Cranberries and whatever else you like or have on hand. I threw in an avocado and sunflower seeds. Hard boiled egg or toasted nuts would also be great.

Put all ingredients in a large bowl.

Dressing:
1/3 C white vinegar
3/4 C oil
1/3 C sugar (I used less)
3/4 tsp salt
3/4 Tbsp poppy seeds
squirt of mustard

Combine all dressing ingredients in a jar and shake. Pour over salad just before serving and toss to coat.

*Tips and Tricks: I think the best way to cook bacon is in the oven. Lay the strips out on a broiler pan or a rack in a cookie sheet lined with foil for easy clean up. Do not overlap bacon. Place it under the broiler for 3-5 minutes depending on desired crispness. This is faster, leaner, and less messy than stove top.
