This is an easy side dish that my daughter told me about. It’s so good you won’t want to save it just for Pesach.
2 red onions, thinly sliced
8 to 10 potatoes, peeled and thinly sliced
1 red pepper, cut into thin strips
2 to 3 tablespoons onion soup mix
4 tablespoons olive oil
Preheat oven to 350 degrees. Layer ingredients in the order listed. Cover tightly with foil and bake for 2 to 3 hours.
