Coat the bottom of a large frying pan with oil (about 2-3 tablespoons) and lightly fry potstickers over medium-high heat until nicely browned on both sides, about 7-10 minutes. Remove from heat and set aside.
In a large soup pot over medium heat, heat two tablespoons olive oil. Add mirepoix and sauté until onions appear translucent. Add broth and bring to a slow simmer. When the soup gets some energy, toss in the spinach and stir in soy sauce and sesame oil.
When the soup is officially simmering, add the potstickers. Ladle soup into bowls and garnish with cilantro and a heaping spoonful of chili onion crunch or hot sauce. (Make sure you have extra spoons on hand... never underestimate the charisma of Trader Joe's Potsticker Soup's On!)
