Aaaaand your conclusion was ?
Since this is clearly very important...
Onni would eat plain cheese pizza, being allergic to everything else.
Tuuri would probably try the pizzeria's daily special with locally grown veggies, as long as they were fresh and non-disgusting.
Mikkel would get pepperoni.
Sigrun would also take the pepperoni, but she would pour a generous amount of Sriracha hot sauce on top.
Emil would try to be cool like Sigrun and cautiously put a little hot sauce on his. He would regret this very much.
Lalli would steal Emil's pizza, not much minding the sriracha.
Reynir would cause much bewilderment by wanting anchovies on his pizza.
Excellent choices. Our conclusion was a bit different (and because memory is imperfect, this account is not exactly what was decided then):
For Sigrun, the one with the most meat (I'll add a ton of hot sauce because you're absolutely right). With extra meat.
For Mikkel, a big hearty pizza, the kind with cheese and potatoes; possibly extra lettuce or a salad on the side.
Emil, I don't remember for certain, but a pretty simple one so as not to spill anything.
Lalli would take the first one on the list (which also usually happens to be the one with least ingredients) and proceed to steal ingredients from his neighbour
For Reynir, Windy suggested one with fish IIRC, but I feel like he'd take an exotic one with pineapple and banana. Possibly extra anchovies because why not
Tuuri will want to experiment and either take the same as Reynir, or compose one for herself. Either way, she'll trade slices with everyone else (maybe she's not that satisfied with her order?)
edit: I hadn't finished reading the thread. Windy gave an account closer to what we had decided at the time.
I had forgotten about the pizza cancer
