Place cauliflower florets in a food processor and pulse until they resemble fine crumbs. Transfer to a microwave-safe bowl, cover with a paper towel, and microwave for 5 minutes.
Spread the microwaved cauliflower on a clean kitchen towel to cool. Once cool, wrap and squeeze out as much moisture as possible.
Return the dried cauliflower to the food processor. Add flour, garlic powder, and salt, and pulse until a sticky dough forms.
Transfer the dough to a floured surface and work in more flour until almost no longer sticky. Divide into 4 parts, and roll each into a long rope, no thicker than 1 inch. Cut each rope into 1-inch pieces to form gnocchi.
Boil the gnocchi in salted boiling water for approximately 3 minutes; remove with a slotted spoon and set aside.
Heat a nonstick skillet over medium heat and add a drizzle of olive oil. Sauté the gnocchi in batches until golden brown on all sides. Serve with preferred sauce.
