Summarize this article:

Many people enjoy eating pumpkin seeds raw. They're a fairly nutritious food as they are rich in fiber and a good source of magnesium, copper, selenium, and zinc. If you're vegetarian or vegan, pumpkin seeds can be a healthy snack as they're rich in protein.  Most people can eat pumpkin seeds without a problem, especially if the shells are fully removed. However, if there are small traces of shells remaining on the seeds, you may get a slight stomach ache. If you're serving pumpkin seeds to kids, it's a good idea to be extra cautious about removing the shell to prevent choking. There are many different ways you can prepare pumpkin seeds. One way is to fry them in olive oil. Spread out some olive oil over a frying pan. How much you will need depends on how many seeds you are frying, but it should be enough to coat the pan.  Allow the oil to heat for a few minutes and then throw in your seeds. Cook the seeds over the oil until they begin to make a popping noise. From here, add about a tablespoon of table sugar. Continue frying until the seeds pop again. Remove the seeds from the heat, let them cool, and enjoy. You can also roast the pumpkin seeds in an oven heated to 375 degrees Fahrenheit. Then lay the seeds out on a baking pan.  If you like your seeds plain, you can put them in the oven as is. Some people prefer to sprinkle them with curry powder, chipotle flakes, or cayenne pepper. Clove, cinnamon, or nutmeg can be used for sweet pumpkin seeds. Bake the seeds for about 20 minutes, or until they're golden brown.

Summary:
Have the seeds as a snack raw. Fry the pumpkin seeds. Roast the pumpkin seeds. Finished.
