1st one: The spaghetti would probably have way more success if it was boiled a little bit just to get that middle part a head start, as it needs to be surrounded by 'liquid' (that includes the beef fat and tomato juice and all that yummy stuff from normal spaghetti.

2nd one: Someone mentioned it below, is that it's like a reverse stuffed pepper. Just if you prefer the meat to the pepper. Also way easier to stuff I guess, since you just wrap it in meat.

3rd one: It's just a ground beef casserole. This one is actually rather common if you're like me or a friend of mine and tend to get wholesale ground beef, and just don't have enough for a 'normal' portioned amount for something else, and meatloaf isn't on the menu.

4th one: Speaking of meatloaf… it's just a cheese lasagna but instead of riccota you have cream cheese. A little different but can still sub in the normal stuff if that's your jam, since Cream cheese is way cheaper than ricotta by volume. Inside of a meatloaf.

5th one: Cottage pie without the cottage. Or the pie. It's a friggin' meat hill. Again, can easily be swapped out if 1: You don't regularly keep pie crust in the house, 2: add in sauce, or 3: Just meat and potatoes. … If you're a protein junkie then this is a good one.

6th one: The … literally version of a "poor man's beef wellington." I forgot the name of it, but I have seen this being sold in either an asian market or a Mexican one. Not sure which, but it wasn't as large as the one in the video, and was much 'thinner'. Bought it, ate it, was pretty good. Of course, recipe can be improved if you like mushrooms diced up in there, maybe throw in some spinach just to have them in there.

7th one: A different way of doing #4 above. Just with more potato than meat, and an attempt at 'gravy' being the bbq sauce. Personally I'd just get a gravy, or better yet, make one from the juices from the ground beef and make a roux from the stuff left in the pot. Waaayy tastier and can adjust it for flavoring, therefore you can get the meat, potatoes and gravy all at once.
