As an alternative, I suggested we make rice. I was thinking rice cooker, but my husband thought I meant the same way I make chicken and rice, and when I thought about it, that did sound like a good idea.
5 pound brisket
1 whole onion (we used vidalia, 'cause that's what we had), halved and sliced
2 cups rice
3 cups water, adjust to taste
Italian dressing, to coat meat because some people aren't organized enough to use a real marinade
Preheat oven to 375.
Pour rice in pan. Add onions. Add water to cover. Massage Italian dressing into meat. Flip, and coat other side.
Cover and bake for appoximately 1.5 hours or until meat is tender and rice has absorbed the water.
Both the rice and meat came out very flavourful and tender. Meat was cutable with a plastic knife. Dressing was nicely absorbed by both meat and rice.
