Season both sides of tilapia with salt and pepper if desired; set aside.

Heat oil in large skillet over medium heat.

Add garkic and kale; cook, stirring frequently, for 1 minute.

Add tomatoes (with juice); bring to a boil. Reduce heat to low.

Place tilapia fillet on top of kale mixture; cook covered, for 1 minute. Gently turn tilapia over and cook for 2 to 3 minutes, or until tilapia is cooked through and flakes easily when tested with a fork.

Remove from heat and serve.
