In a large wok, add about half of the oil and garlic and cook on high heat until the aroma comes out from the garlic. Add in raw chicken and cook until chicken is almost completely cooked. Add in rice, onion and remaining oil and continue to cook. Then stir in pineapple chunks, fish sauce and oyster sauce. If desired, add in chili peppers. Stir in cashews.

Shift the rice to the side of the wok, so that you have some empty space to cook your eggs. Add eggs into the empty space and stir them to scramble them as they begin to cook. Once all the eggs are finished cooking and are completely scrambled, add it back to the rice. Stir and cook a few more moments. Add in scallions and cook 1 more minute. Scoop rice into pineapple shells and serve.
