Add tomatillos, onion, jalapenos, and pumpkin seeds to another pot. Bring to a boil then reduce to a simmer. Once tomatillos soften, drain the water.

Remove garlic and onion from the stockpot and pour in salsa from the blender. Add oregano and continue cooking for about 20 more minutes. Adjust salt to your liking.
