According to the cube rule of food, pasta is a type of nachos. I have no idea how this is helpful though.
My own 2 cents is that something like string theory is at play here... the dimensionality of the sandwich is all wrapped up in what appears to be a 1-dimensional carbohydrate noodle, but if you could zoom in with a crazy powerful electronic microscope, theoretically the pasta might actually look like a stupendously long sub sandwich.
My personal rule is "carbohydrate bases are mostly interchangeable".
If a topping works on bread/toast, it also works on a pizza base, Yorkshire pudding, noodles, chips (fries), rice, pasta, pancake etc
For example - tomato sauce, mozzarella, basil and pepperoni works on a pizza. I can confirm it is still delicious on toast, pasta, rice, Yorkshire Pudding, chips.
Controversially, this means sweet pancake toppings should also work on pizza bases or noodles.
Therefore this would mean that Nutella on pasta is probably pretty nice.
The toppings should still follow normal food rules, so maybe not so much the bacon, unless sweet bacon is a thing that exists? But otherwise, yeah - no reason why not :)
