That happened to me today. I had every intention of making oven-dried tomatoes. Similar to sun-dried, just roasted in the oven a bit and dried out. But I didn't follow a recipe, and what I wound up with instead were oven-roasted.
They were still pretty tasty, and I ate them on top of some spinach leaves. Not a total loss.
I cut up some cherry tomatoes and then took some olive oil with a bit of dried oregano mixed in and drizzled over the top. Then I put them in the oven for about 25 minutes on 375. What you get is some oven-roasted tomato goodness.
