Our Tomatoes and mysterious peppers

So I can not take credit for actually growing these yummy garden tomatos, but aren't they purtty??? They taste SSSOOOOOO good. When we first moved in there werent any actual tomatoes, just little yellow flowers. So in a sense, yes, I have helped them grow....by watering them daily. We also have these little peppers, that we havent figured out what they are. At first we thought they were going to be green peppers. But then they grew, and look like jalapanos. But they arent hot or smell like them. ? So I picked them - and one has gone as red at the tomato in the last picture. Who knows.
