Tested this one. It was plenty for 8 people. 
Was Excellent with following caveats:
- When guests were late, tomatoes sat in the oven too long and ended up soggy and not identifiable. Try to time it better (make the guests wait rather than having soggy tomatoes?).
- Ricotta must be full strength of fat – our case, 7% fat, did not melt, just sort of sat as a white residue..
- Definite need for salt and Pecorino or Parmesan
- For those who tolerate bacon, you can add a bit of it for the taste (see step 3), but it is not at all necessary.
