Cauliflower Soup with Grilled Cheese Croutons

Now that most of the trees have turned and some are even bare, it’s really starting to feel like fall to me. The mornings are cool and crisp and so are the afternoons. That is sweater weather. Scarf weather and, my favorite, soup weather. I’m not going to lie. I’m kind of obsessed with this soup. It is so comforting. And, you guys, there are grilled cheese croutons on top. I mean really, I’m not sure it you can get anymore fall comfort food then a pot of tummy warming soup with grilled cheese croutons.

I first tried cauliflower soup the same night I tried the chickpea cakes at a local restaurant.  When the server sat down this little bowl of soup in front of me, I didn’t even happen to catch what it was before I started noshing on it. It was gone in about two seconds. When the server came back I asked ‘What was that?” He replied cauliflower soup with a drizzle of olive oil.

Say what?! That’s it? I was expecting some big long adjective filled description. But no. Again, friends, simple wins out.

I did want to make it a little more of meal so I made a grilled cheese sandwich using the Kerrygold Blarney Castle Cheese and diced it up into little croutons and put it on top of the soup. Like this soup, I’m kind of obsessed with Kerrygold Blarney Castle Cheese right now. It’s a gouda style cheese and so creamy and flavorful. That being said, you could easily use your favorite kind of cheddar other kind of cheese you like.

Whatever you do, make this soup soon.
