I would run out of my house, gather some wood, make a wood pickaxe, procede to a stone pickaxe, mine some iron, make some iron armour and a sword. Who else would'nt? (lol) I would run out and make a cobblestone home and cook some porkchops I had in my fridge. The zombies would not be able to break the cobblestone and resort to dying outside. I would take their rotten flesh, boil it, and nom nom nom!
