My attempt to translate page 2:
Panel 1
Mashiro: "I want to try eating this."
On box: Oat Meal
Mashiro: "Foreign country-ish."
Kobeni: "Did you buy it to try?"
Panel 2
(I don't know how to translate the sfx. Mashiro's expression tells it better than words.)
Kobeni: "Was it no good?"
Panel 3
Kobeni: "I made it into cookies."
