I’m going to guess based on the picture on the tube that the Amerikansk sauce is more like Thousand Island dressing.
Chicken Porridge!

A very healthy and tasty alternative 
That’s actually a literal translation of the name. “Smörgås” (literally “Butter Goose”, but we’ll let that one slide for now) means sandwich. Once Sweden joined the EU, going around calling things “kaviar” wasn’t entirely popular.
As previously mentioned, basically thousand island dressing, i.e. ketchup and mayo. Associated with the US as revenge for associating meatballs with us 
Pretty much as described, basically cooked blueberries thickened with some potato starch. Good source of vitamins, and excellent in a thermos on a cold day.
Ah, the infamous snus. Basically moist tobacco which is either packed manually (if you drive a semi truck for a living) or comes packed in little teabags, and is carried around beneath the upper lip, giving the male Swede the appearance of constantly pursing his lips and appearing in deep thought. Also a common emetic among Swedish teenagers.
Strangely classified as a narcotic in the rest of the EU.
The flatbread I think you’ll find quite unique, as well as the more commonly sold knäckebröd.
Yeah, the Japanese breakfast is not too far off the mark. If you stay at any ryokan, there isn’t a breakfast ‘menu’, there’s just breakfast - take it or leave it. Usually it has rice, fish, tofu, salad, some kind of soup, dried seaweed, assorted boiled vegetables, eggroll, stuff like that. Not really my breakfast of choice, but by god do you feel good after eating it. Ham, eggs and toast makes me sluggish in the morning, but a Japanese breakfast is a real energy boost.
Having said all that, many people in Japan have something like a boiled egg, toast and coffee for breakfast these days.
“Also good is you suffer from diarreah,” it says in the product description. Thoughts?
Blueberries are supposedly good for relieving diarrhea because of their tannin content.
What about a breakfast roll? 
I used to make them for the builders heading out to work in the mornings, white demi baguette, butter, rashers, black and/or white pudding, red sauce.
Egg was an extra, as were hash browns or wedges.
Wouldn’t eat one myself!
No sausage?
Look closer. In the sentence that Bambi quoted, there’s a big difference between “is” and “if”.
Ah! 
My brain apparently edited that in my reading.
