Potato and Cauliflower Gratin

It had been about three weeks since I'd last talked to my mom. Daily life, weekends brimming with things to do, obligations, homework and all around exhaustion taking hold at the end of each day prevented us from talking as frequently as we would've liked. So last Saturday was the day we scheduled to be able to talk and catch up. Yes, we actually had to calendar the phone call.
My husband and the boys were at an early morning Cub Scout event and I was out running errands when she called. I was expecting her call even though I was at the grocery store. It was early and there weren't too many folks there at that time of the morning. But despite my opinion that people who talk on cell phones in public are rude, I was one of those rude people.  It couldn't be helped or rather at least I didn't care all that much if I was being rude. I wanted to talk to my mom. We talked and talked as I shopped the aisles. The epitome of rudeness, I know. Yeah, I even checked out with my phone stuck to my ear, completely ignoring the checker! Yikes.
We talked and laughed as I made my way home. (Hands free of course!)  We talked about my boys, talked about the food, what we got on sale, and the new recipes we'd tried recently. What was good. What wasn't. She told me about this recipe, from Cuisine at Home that she adapted by adding cauliflower along with the potatoes to this Potato Gratin to make this amazingly delicious Potato and Cauliflower Gratin! The original recipe calls for Swiss cheese, which I didn't have at home, but she told me that she just uses any cheese she has on hand. So I used a blend of Asiago, Havarti and White Cheddar, since I had a little bit of each and it was incredible! Can't go wrong with Asiago and Havarti cheeses!
I made these creamy, cheesy, yummy potatoes that night and it was just what I needed to soothe my weary soul, comfort food and a long phone call with my mom. The perfect day! Thanks Mom, I love you.
