Pierogi Lasagna

Pierogi Lasagna is a great way to use up leftover mashed potatoes and tastes like a creamy, cheesy, mashed potato casserole.

Ingredients

• butter for greasing pan ( I use Pam)
• 6 cups leftover mashed potatoes (Instant potatoes for 6)
• 1 cup  shredded sharp cheddar cheese ( or as much as you desire )
• 9 lasagna noodles boiled 
• 1/2 lb. bacon, fried, drained & crumbled
• salt and pepper, to taste
• sour cream for serving (optional)
