Unless I have a good read, I'd probably just call and see what happens on the turn. Assuming a blank (about half the deck), I may minraise him back on the turn to get a free showdown, or push right there and hope he calls with a pair + draw. Or you could call him down and hope a draw doesn't hit or the board pairs in case he had 2 - tough spot, try to figure out what his min-raises mean - surprisingly, people are generally consistant with them.
