In a small sauce pan, heat the chicken broth until simmering and keep warm.
Meanwhile, in a large non-stick, high sided skillet over medium heat, melt the butter.
Add the chopped onion and cook until softened, stirring occasionally, about 5 minutes.
Add the garlic, seasonings and apple cider. Cook, stirring and allowing to boil for 1-2 minutes.
Add the rice and stir until well coated.
Then begin adding the warm chicken broth, about one cup at a time.
After each addition of broth, stir for a bit, then put a lid on the pan. Cook until the broth is mostly absorbed, which will take about 5 minutes each time.
Once all four cups of the broth have been absorbed by the rice and it is tender (which will take a total of 25-30 minutes), stir in the pumpkin and most of the feta cheese.
Stir well and cover the pan and continue to cook for a few more minutes.
Taste, adjust seasonings and garnish with the rest of the feta cheese. Top with a little cracked black pepper if desired.
