When wife and I were first starting out, and lived in an apartment we cooked steak, chops and chicken on an indoor electric counter top grill. Sometimes we would char it and then put it un a crock pot. They work well. Quite a few models out there from $ to $$$$$. Check ebay listings. And Craigslist too.
