Cheesy Onion Casserole

Southerners are in love with sweet onions, and the sweetest variety is grown near us - in Vidalia, Georgia. Since Vidalias have become so popular, everyone - including me! - seems to be developing new onion recipes.

    Very good, however I used mozzarella in place of swiss.

    This is really cheesy and filling. We ate all the bread off it the night I served it. I topped baked potatoes with the leftovers. Excellent!
