Do they have crock-pots there? I make my Sunday roasts in the crock pot. Fully cooked, tender, juicy-it literally falls apart, and doesn't heat up the kitchen either.
Maybe you could get one and convince him to try it. Put the meat in the pot, throw in about half a bottle of dark beer, some Bisto granules, and some soup mix if you have it. I chop and add carrots, turnips, and parsnips.
Takes about 6 hours to cook on high. I cook mine longer, put it in at about 9-11 am, depending on when I get up, and we eat 6:30-ish to 8-ish.
Trust me, it's fantastic, and the leftovers are wonderful too.
