Is there a way to do a 2D FFT on the Prime?

RE: 2D FFT
create two Vandermonde() of the size you want.
and use the double summation that defines 2D FFT

RE: 2D FFT
"Vandermonde"? Even google translate gives up.

hp
menu>>matrix>>Create>>Vandermonde vandermonde([1,e^(2pi*i/3),e^(4pi*i/3)]) to create 3x3 matrix and use the definition for 2D FFT: https://www.mathworks.com/help/matlab/ref/fft2.html
