One of my favorite meals in my singe days was a pot roast. I was very broke so small pot roast, lots of carrots and taters. Eat a little pot roads, all of taters and carrots. Add more taters and carrots water and cook it some more. I could eat for several days before the meat was gone. Just get a cheap pot roast with a lot of fat. After a week of cooking it it was tender.
I used to cook a lot of stuff on the gas grill in the back yard.
That is really my grill in my back yard. Even if it snowed I could gook a chicken out there.
Buy whole chicken. Cut it in half and throw away that colostomy bag of stuff and grill for 20 minutes, flip, 20 minutes, flip and 20 more minutes. Eat 1/2 chicken. Burp. Nuke other half the next day. Burp. Cheap meal.
