Cut the pork loin into cutlets, about 1/2 inch thick
Season the pork cutlets with salt, pepper, and onion powder
Place the cutlets into a large roasting pan, partially overlapping the cutlets
(when overlapping cutlets, stack like crackers on a cheese and cracker tray)
In a medium saucepan, melt the margarine over medium heat
Add the curry powder and mix thoroughly
Cook for about 3 minutes
Add the crushed pineapple
Cook for 10 minutes
Add the chicken broth to the saucepan
Increase the heat to medium-high to high (depending on how closely you'll watch the pot)
Bring the mixture to a boil, stirring frequently
Boil for 10-15 minutes, until the sauce thickens
Pour half the mixture over the top of the pork cutlets
Reduce the heat of the saucepan to low and keep the sauce warm
Roast the pork, uncovered, for 40 minutes
Turn the pork cutlets over, continuing to have them overlap
Pour the remaining sauce over pork
Roast the pork for another 20 minutes
Remove the pork from the oven
Loosely cover the pan with foil
Allow it to rest for 10 minutes
