I had a bunch of leftovers so I used them all, and I made this. I had a little bit of several cheeses left from other meals and some homemade ricotta, too. I had leftover hamburger meat, and I had some cream. I used the cheeses and the cream to make an Alfredo type of sauce. I had no parmesan, ironically, so it's not a real Alfredo sauce, but it came out very, very well. Then, I boiled some penne pasta and drained it. I mixed my sauce and the pasta in a casserole dish. I then seasoned the mixture, and I added some mixed vegetables and the cooked, crumbled hamburger meat. I put dollops of the ricotta cheese here and there. I then sprinkled the rest of the leftover cheeses on the top and baked it. It was so ooey gooey and cheesy!! The flavors of the cheeses really shone through. It was very rich and creamy. I ate some, and now I need a nap! 😉😁🤣😋😍 In the words of my girl, Julia Child... bon appétit!!! And bon it was!!!
