Add enough canola oil to cover the bottom of a large skillet. Heat over medium to medium-high heat.
Slice squash. Sprinkle slices with salt, then roll in cornmeal to coat.
Add all squash slices to the hot oil and allow to fry for 5 minutes without turning. Turn and continue to fry, flipping every so often, until crispy and golden brown on both sides, 10 to 15 more minutes. Serve immediately.
