I now have a stove!
I found this Paula Deen Mac and Cheese recipe, which I doubled (for a big group) and modified a little bit. It was delicious and a big hit - we had just enough left over for some lunch the next day, and it warmed up quite well!
Crock Pot Mac and Cheese
1 (32 oz) box macaroni
8 tablespoons butter
2 pkgs shredded cheddar cheese
3/4 cup sour cream
2 (10 3/4 ounce) cans condensed cheddar cheese soup
2 cups milk
1/2 teaspoon salt
1/2 teaspoon pepper
Step #2: In a saucepan, melt butter and cheese until melted. As you can see, since I didn't have a stove, I just turned the crock pot on high and did it in there. It took a long time, and I recommend the stove!
Step #3: Pour mixture into crockpot, and add sour cream, soup, milk, salt and pepper. Mix.
Step #4: Add macaroni and stir until covered.
Step #5: Cook on low for 2 1/2 hours - stir occasionally.
