Preheat the oven to 350 degrees F (175 degrees C).

Bring water and rice to a boil in a saucepan over medium-high heat. Reduce heat to low, cover, and simmer until rice is tender, about 20 minutes.

Combine pork, cooked rice, and broccoli in a large bowl. Stir in soup and mayonnaise; season with pepper and curry powder. Transfer to a 9x13-inch baking dish; cover with aluminum foil.

Bake in the preheated oven until evenly heated through, 45 to 50 minutes. Remove foil for the last 5 minutes.
