Are you a good cook?
And do you have a "signature" dish?
I'm a very good cook and I make many different cuisines: Mexican, Vietnamese, Italian, Indian, middle Eastern, etc.
I have a few signature dishes and the one I make most often these days is something I made up:
Gnocchi with split, tiny tomatoes, fresh garlic and cilantro tossed with olive oil and a little lemon or lime juice, served at room temperature. Simple and it's a hit every time.
