This spinach salad is one of my favorite family recipes. Fresh greens, mushrooms, warm crumbled bacon, cottage cheese and Swiss cheese come together for a flavorful and unique salad that's sure to impress! The poppyseed dressing is the perfect sweet addition to make this a crowd favorite.
Add all ingredients to a blender and blend until smooth. Taste and adjust ingredients, to taste: more vinegar if you want it tangier, more sugar if you'd like it sweeter.
Refrigerate until ready to use. Shake well before serving on salad.
Add the spinach and lettuce to a large salad bowl. Top with remaining salad ingredients and toss lightly to combine.
Drizzle with desired amount of dressing. Serve immediately.
