Fleishig salads and cold meat sides — the substantial half of a Shabbos table or a kiddush, delivered by the container.
Meat salads are the ones that count as food. Chicken salad, cold cuts dressed and sliced, meat-based sides that go beside a main rather than in front of it — this is what fills out a Friday night table or a men's kiddush where the fruit and dips are not going to be enough.
Being fleishig, they commit the meal, so order them knowing what else is coming: no dairy dessert on the same table, no cheese board alongside. Kashrut is the first filter on any meat product and is listed on every store's page. Choose the delivery date at checkout for the day it is being served, since these keep less well than parve salatim.
