I wonder how well rollinia fits the bill as a staple food? I hear it's very filling.
I never found the desert Tropical fruits very filling.
Some other people probably didn't either, as they could eat quite a few at a sitting.
Exception is probably Pouteria campechiana, Canistel, Yellow Sapote, because of its dense texture.
Maybe Diospyros, Black Sapote too, not overly sweet.
Avocado yes because of its oil content. Durian is a yes.
( watery light flesh tropical Avocados not as filling as Hass type varieties )
Dabai, Canarium odontophyllum which is something like a cross of Avocado and olive was very filling.
Pine islander, thanks for the link for Capsicum chinense, Ají Dulce en el Huerto, I knew about Aji Dulce, but that's a new one.
