This just came up in a pot that had a pepper plant that died when I used a vinegar/water solution to kill the ants on it. The leaves and tiny white flowers look like the pepper plant, but this is more like a bush and the previous plant was more like a small tree. I'm new to gardening and hoping for better luck if this is a pepper plant.
Can Someone Tell Me if What I Have Is a Bell Pepper Plant?

I agree your volunteer plant seems to have leaves that look like Bell Pepper seedling leaves.
The vining pattern is not something I can find an image that matches.
I would allow this mystery plant to grow and see if it produces any peppers.
I also am listing some links about ant control for future reference.
