Chuck wagon potatoes

1/2 onion, finely chopped
2 teas garlic, finely chopped (I buy the bottled chopped garlic)
1/4 c olive oil
1/4 cup margarine, melted
3 Tablespoons chopped parsley
3 lbs red potatoes (enough to fill baking pan) cut into bite size pieces
1 lb bacon, chopped and fried
2 cups shredded cheddar cheese
Put first five ingredients in a large ziploc bag, mix together. Add potatoes and toss to coat potatoes. Pour potatoes into a 9x13 pan cover with foil. Bake at 350 until fork tender, about an hour. Remove foil, stir in precooked bacon, put back in oven (uncovered) until brown 15-20 minutes. Remove from oven sprinkle cheese over the top of potatoes and serve.These are really tasty
