Grill, its funner.
Oven not working: reheat fresh pizza on grill or microwave?
Live a little.....eat it cold!
I've done pizza on the grill, but you have to be careful with the heat, because I've burned pizza on the grill as well. LOL
Microwave 1 min. Then 30 seconds as needed.
Grill. Don't EVER reheat pizza in a microwave. It'll become soggy and that's just sacrilegious.
