Cauliflower au Gratin with crispy onion topping

 

I don’t know about you, but I do love a good casserole. Especially those that are creamy and cheesy. This Cauliflower au Gratin is both, and more, with the crispy onion topping, like that on a good green bean casserole.

This make such a nice side dish with so many things, like my Patient Pleasing Hospital Meatloaf.  You can make ahead and bake close to serving time too.  And hey, you can even sub similar vegetables for the cauliflower too, or a combination.  Others that would work are broccoli, carrots, turnips and potatoes.

…simply tomato soup

There are few things as comforting as a bowl of “simply tomato soup.”  Recipes can be found of assorted varieties.  All over the tomato soup map.  For me, I don’t care for anything fancy… and many are too heavy on the basil for me.  It’s ok, but not a big fan, and a little basil goes a longggg way. Tomato soup need not be fussy… just tomato soup.
