As I said on that TJ’s thread, most of the frozen dishes I buy (occasionally) don’t need any doctoring: Indian, Korean (except fried rice), Greek, flatbreads (in the pizza section), and tamales.
I don’t consider saucing things that would typically be sauced (dumplings for eg) tweaking.
Elsewhere, Whole a foods used to make a frozen Pad see ew that was pretty good if you reheated it correctly, but it must not have been popular, because they only have the Pad thai now. The WF branded frozen samosas don’t need any adjusting (re OP “meant to be eaten as a meal” — I have eaten a few as my meal 
)
