They skipped some pretty important stuff that should have happened before the cooking competition: one that inspired what MC makes and one that helps him technique-wise. I really don't see how this is going to work, unless they stick in some flashbacks while he's cooking or something...
Why'd they cut nearly all of his fight against the soldiers in ch36? It was so cool in the novel!
About the two untranslated bits of dialogue in ch8:
グレンほどでわないけど = not as many as Glen, though
俺の方がランク上なのに... = even though I'm a higher rank...
