Have not used either of those, but use frozen on a regular basis. When we get fresh here, they
are very spendy and I just like to gobble them up.
But several times a year I take joannie's Prawn, Mango and Avocado Salad to pot lucks using the frozen chunks. Also use them for salsa.
At work I get them in 40# boxes and often thaw them slightly and add to breakfast fruit.
enjoy,
Nan
