This is a good side if you have some time...it bakes for about 90 minutes (or longer depending on your oven).
4 peeled medium potatoes sliced on a mandoline or on the side of a box grater that has the three openings
3 Tbl olive oil
1 large onion, sliced thin
1/2 cup finely diced green pepper
1 minced clove garlic
2 Tbl butter
1/2 tsp salt
1/2 tsp pepper
Soak the sliced potatoes in a bowl of water, while prepping the rest of the ingredients. Drain and dry them as thoroughly as possible with paper towels.
Start sauteing the sliced onion in the olive oil over medium heat and when they start to caramelize, add the green pepper, garlic, salt and pepper. ( this will take 15 to 20 minutes) Continue to saute for a few minutes more. Combine the onion mixture with the potatoes and press into a quiche pan or pie pan, making sure that the potatoes are lying flat on the top. Dot the top with the 2 Tbl butter. Place a round of parchment paper over the top that's been cut to fit inside the pan and press firmly on the potato mixture. Bake at 300F for 60 minutes. Remove the parchment and continue baking at 350F for about 30 more minutes or until the potatoes are tender.
