Sorry, I missed that part of the rules, I'll refrain from doing it again
I just put on a load of onions, 6 large yellow, to caramelize. I did not add the peppers but will as soon as the onions cook down a bit. The recipe whose link that I mistakenly posted, is as follows:
Ingredients:
2 tablespoons extra virgin olive oil
4 bell peppers, stemmed, seeded and cut into 1/4-inch strips
1 large yellow onion, peeled and sliced into 1/4-inch strips
1/2 teaspoon salt
1/2 teaspoon freshly ground black pepper
2 teaspoons balsamic vinegar
1 teaspoon fresh thyme, finely chopped (or 1/2 teaspoon dried thyme)
Instructions:
Heat the oil in a large skillet over medium-high heat. Add the onions, peppers, ¼ teaspoon salt and ¼ teaspoon pepper.
Cook, stirring every few minutes, until onions are caramelized and peppers are tender and slightly browned, about 15 - 20 minutes.
Add balsamic vinegar and thyme and turn heat to low. Cook for a few more minutes. Taste and add remaining salt and pepper if desired. Serve hot or at room temperature.
I used 3-1 butter/olive oil and I think that the ratio of onions/peppers is not what I want, I'll use 1-1. Since I intend to use this as a burger/steak topping, I'm thinking of adding mushrooms with the peppers.
