We had a pork chop repeat last night as the main course, but this is quite possibly my favorite side dish:
About 3 lbs red potatoes, wash and dice into bite-size pieces. Do not peel the skins.
Heat your oven to 400
Put the diced potatoes in a large baking dish (13x9), and add about 1/4 cup of EVOO (enough to cover all of them but not soaking)
Season with oregano (lots, like 2-3 tbsp), garlic powder, black pepper, and a little kosher salt. Stir that all around so they're evenly seasoned.
Bake for about an hour and stir them a couple times during that hour. When the potatoes are soft and you can cut right through them, they're ready.
Simple but delicious and works with nearly any chicken/steak/pork dish!
