That recipe calls for toasting the hoagie buns with butter and garlic salt, but I didn't do that so probably I should have added garlic salt to the meat like you suggest.
My wife wanted the Insta Pot. It's basically a digital pressure cooker, so it can do things like canning and quick versions of crockpot recipes. I like it for making yogurt as it has a setting for that. But I'm not sure we get enough use out of it to make it worth the space it takes up in the kitchen. Plus either my wife or I is home most days to be able to cook dinner, so we might use it more if time for making dinner was an issue.
@GSG, what do you make in the Insta Pot? And how do you like it compared to traditional cooking or even crockpots?
