I bought 2 London Broil steaks on Saturday for a cookout on Sunday. We only needed one and left the other in the fridge. Last night I realized that I never put it in the freezer, so I threw it in the crockpot with some stew veggies. It had been in the fridge for 4 days. Before I serve it to my BF, do you think its safe to eat? It looked and smelled fine.
