I checked the display in the link you posted. Unfortunately, there isn't a quick way to use this display with the Mini-Breakout Board, and I'm not aware of any sample code for it besides the one provided by Adafruit.
You would have to write a new library for it. You could use the one provided by Adafruit as guidance. Additionally, the I/O pins on the Mini-Breakout Board uses 1.8V logic, so you have to make sure there is logic compatibility between the external hardware and the Mini-Breakout Board.
The display uses the SPI interface, so you should program the SPI to communicate with the display. I recommend you to look for the datasheet of this display to know the details of it.
I know this is not the answer you expected, but as I said, there aren't sample codes for this display. The only way to try to use it would be to program your own library.
I'm aware of the fact that the IO's are 1.8V , I'm using a level shifter(see link below) to solve this issue.
I know the display uses SPI for communication and already had a look at it's datasheet.
Like you said, this wasn't exactly the answer I was hoping for but thanks for you advice.
