In a large bowl using a spoon (or use your hands), mix together all the ingredients except the olive oil. The mixture will be sticky.
Heat a large skillet over medium heat. Add the olive oil.
Scoop a portion of the mixture, about 1.5-2 Tablespoons in size, and drop into the hot pan. Slightly flatten into a patty shape using the back of a spoon or spatula. Repeat with remaining mixture until you have 8-10 patties on a skillet, depending on the size. (Don't overcrowd the skillet).
Cook for 5 minutes, then flip, and cook for an additional 3-5 minutes, or until cooked through. The sausage patties are fully cooked when an instant-read thermometer reads the internal temperature as 165°F. Transfer to a paper towel-lined plate or baking sheet. Repeat with the remaining mixture.
Serve chicken sausage patties warm. Store leftovers covered tightly in the refrigerator for up to 1 week. Reheat as desired.
