Cheesy Beef Pasta

• 1⁄2 pound lean ground beef (15% fat)
• 1 onion, diced (about 1 cup)
• 2 cloves garlic, minced, or 1/2 teaspoon garlic powder
• 1 small zucchini, chopped (about 1 1/2 cups)
• 1 jar (24 to 26 ounces) tomato based pasta sauce
• 1⁄2 teaspoon dried basil
• 1⁄2 teaspoon dried oregano
• 1⁄4 teaspoon hot red pepper flakes (optional)
• 12 ounces rotini pasta (about 4 cups)
• 2 ounces shredded cheddar cheese (about 1/2 cup)
• 6 ounces shredded mozzarella cheese (about 1 1/2 cups)

In a large skillet, cook beef, onion, garlic and zucchini over medium-high heat (350 degrees in an electric skillet) until meat is browned and broken into pieces. Drain any fat.
Add the pasta sauce, basil, oregano and red pepper flakes, if desired. Bring to a simmer and cook on medium low (275 degrees in an electric skillet) for 15 minutes.
Cook the pasta in boiling water according to package directions.
Drain the pasta and add to the sauce in the skillet. Stir in the cheese and cover until the cheese is melted.
Refrigerate leftovers within 2 hours.
