Possible but I regret not probable. This can be achieved with hormones and
even by grafting but these are quite specialised methods. Interestingly, it
is possible to graft on to potato and obtain a crop of both but in very
reduced quantities.
You will find new growths appearing from near the break unless this was
below the cotyledons.

I think the cat rolled on one of my tomato plants and it broke off. I
stuck
it back in the ground just to see what happens. Is it possible that it'll
reroot itself into the ground?

Thanks!
