Cook chorizo in a large skillet over medium-high, stirring to crumble, until browned, about 6 minutes. Transfer to bowl with rice; cool 10 minutes. Add cheese, eggs, and salt; stir to combine. Form into 8 (3-inch) patties, and dredge in panko, pressing to adhere.
Heat oil in a large skillet over medium-high. Cook rice patties, in batches if needed, until golden brown, about 4 minutes on each side. Transfer to a plate lined with paper towels. Top with guacamole, if desired.
