Panel 1: As Elly prepares his lunch, Mike asks "EGG?? You're giving me EGG sandwiches for lunch?" (In the original, Lynn revealed that she thinks that there's a 't' in the word 'sandwich'.)
Panel 2: Since she's already made the egg salad and can't simply throw it out AND since she doesn't care what he thinks, she sniffily says "This is a perfectly good lunch; I want no complaints."
Panel 3: As he walks off with lunchpail in hand, he asks himself how he's supposed to sit next to Deanna Sobinski with egg breath.
Summary: What we see here, of course, is the end result of a collision of two unpalatable phenomena. Why it is that Lynn got a contract when Mike acts like no child who ever lived and Elly acts as if his opinion is less than optional is a mystery that not even Freddy and Velma could solve.
ETA: Now that it's the month of March, Lynn brightens the day of her American friends with this banner. Forget her not knowing about the human trafficking going on in Thailand, she doesn't even know how the horrible weather of the last two months has broken snow removal budgets in most of the Mid-Atlantic states or why produce is going to cost more this year.
