N.C. Without long baking times for tenderizing, some cuts of meat are out of the question. A tough piece of meat is a tough piece of meat if it's cooked quick. This forces you to use better-quality stuff. For beef, that often means a sirloin cut. It's going to be more expensive, but it's a trade-off.
Fish is an exception.
Any baked recipe that contains eggs requires at least 30 minutes in the oven. Even a simple casserole will not heat through in that amount of time. They want meat, potatoes and a vegetable. Heaven forbid the elements even touch each other. And anyway, there remains the option of spending a more traditional amount of time making dinner.
