Lots of times I think too late about what I want to eat, and I decide to make something in the stove that's frozen in the freezer. Can I just put the food in the oven without thawing it? The stove is a year old or close to it.

Quite a lot of food is ok to cook from frozen. Often it's labelled as such. The main thing you want to watch out for is food that appears to be cooked on the outside, but remains undercooked on the inside. Consuming that could result in food poisoning, which we can all agree is not a good thing.
