McDonald's cooks its quarter pounders from fresh beef (hasn't been frozen since 2018). Their Roma tomatoes are also, you know, fresh. Just like their lettuce. Their Egg McMuffins are cracked from fresh eggs onto the griddle.
They deep-fry their fries, good luck doing that at home in your microwave.
All their sandwiches are hand-assembled. Buns and english muffins all freshly toasted.
McDonald's is an actual restaurant. They're not just reheating and repackaging. Unless by your standard every restaurant falls under this category...?
