Looks good. One minor thing, those are Knöpfle, not Spätzle. They're basically the same thing and can be used interchangeably, but they have a different shape. Some people prefer the one, some the other. I think Knöpfle are better with thick sauces while Spätzle are better plain (next to sauce, Knöpfle are made to be drenched IMHO) and or with browned butter. Both are excellent with hearty cheese melted into (not like mac and cheese though).

Edit: and I think it's a regional thing as well. Where I'm from, Knöpfle are the preferred variant, where I live now it's the other way around.

Ah, the Rhineland version of Rouladen. We have a slightly different filling. We spread some mustard on the meat, put some thin slices of black forest bacon and a slice of old Gouda cheese on it. We then put some Mett (spiced minced pork) on one end and roll them up. No need to sacrifice an innocent pickled gherkins' life for this dish.

That looks delicious! I didn't know Costco had spaetzle.
