Heat oil in a large skillet over medium heat. Add onion; sauté until translucent, about 10 minutes. Add garlic; sauté for three minutes.

Add ground beef, stirring and breaking up large pieces as it browns, five to seven minutes.

Add remaining ingredients; bring to a boil. Cook for 20 minutes, stirring frequently.

Remove from heat; set aside until cool enough to handle.

Preheat oven to 425 degrees Fahrenheit.

Scrub zucchini; use a vegetable peeler to peel lengthwise strips down the sides of the zucchini.

Place one to two tablespoons filling at the end of a zucchini strip.

Carefully wrap the rest of the strip around it, keeping the filling inside. Then take another strip and wrap it around the other way.

Place packets into a greased 9- x 13-inch pan.

Bake, uncovered, until browned, about 10 minutes.
