The thing about Trader Joe's is their wheelhouse is "satisfyingly feed one 20-50 childless possibly downwardly mobile college graduate with no prep whatsoever, or two to several with no prep that assumes any kitchen skills", and they hit it really well

Oh yeah, their lunch cases are the best around by far
