Cut a fresh pumpkin into one-inch cubes, then steam them until soft (seven to 10 minutes). Toss cooked cubes into a vegetable soup or any sort of chicken-and-rice or pasta casserole. You can also add them into your favorite stir-fry (just do it in the final minutes of cooking so they don't fall apart).
Puree or mash cooked pumpkin cubes into a quick side dish. Add cinnamon or a bit of coconut milk to amp up the sweet potato-like flavor. For a savory alternative, mash pumpkin with regular potatoes, for a side that's higher in fiber, vitamin C, and beta-carotene.
Wash and depulp a couple of handfuls of fresh pumpkin seeds, then spread them out on paper towels to dry overnight. The next day, toss them (with a bit of oil, salt, and pepper or your favorite mix of spices) and bake at a low temperature for around 15 minutes, tossing every few minutes until they turn a golden brown. Eat with dried fruit or nuts for a DIY trail mix.
Grind toasted pumpkin seeds with cilantro, parsley, garlic, lemon, a little vinegar, and olive oil in a blender to create a homemade, low-cal salad dressing. Pumpkin seed oil is delicious and may help to fight off disease, too.
