Tomato Plants look Good

I started growing tomato plants on my window ledge, they look very good. The plants themselves look nice.

I planted them about a month ago but they're already bigger than my hands, they're about the size of dinner plates. The heating system in my home would be keeping me and my plants warm through the colder months. When the tomatoes are ripe, I can push them through a hand grinder and make a sandwich mix. Tomatoes, lettuce and cucumber with mayonnaise and brown bread 😋 

I wonder how big they can grow. Perhaps the plants eventually grow a wooden stem and become tree like, I don't know.
