Wait till they are ripe all the way around.

I'm getting some tomatoes coming from the vine where one half is very red
and the other half is very green. I picked those and put them in a paper
bag but was wondering how to eat those. Should I cut it in half, eat the
red part, and then wait for the green part to turn red?

BTW: Most of the tomatoes ripen evenly.
