1. Prepare the Spaghetti Sauce

1. Cook the Vegetables and Beef:

   • In a large microwave-safe bowl, combine the chopped onion, garlic, bell pepper, and celery. Add the butter and microwave on high for 2 minutes or until the vegetables are softened.
   • Stir in the minced beef, breaking it apart with a fork or spoon. Microwave on high for 2-3 minutes until the beef is fully cooked.

2. Add Tomatoes and Seasonings:

   • Slightly drain the canned whole tomatoes and add them to the bowl. Use a spoon to crush the tomatoes.
   • Stir in ketchup, sugar, oregano, salt, pepper, and water. Mix well.

3. Cook the Sauce:

   • Microwave the sauce on high for 5-7 minutes, stirring halfway through.
   • The sauce should thicken, and the flavors should meld together. Adjust the seasoning as needed.

2. Cook the Spaghetti Noodles

1. Prepare the Noodles:

   • Break the spaghetti in half and place it in a microwave-safe bowl. Submerge the noodles in water and add a pinch of salt.

2. Cook the Pasta:

   • Microwave on high for 4-6 minutes, stirring halfway through. Check for doneness after 4 minutes to ensure the noodles are al dente.
   • Drain the noodles carefully and toss them with a drizzle of olive oil to prevent sticking.

3. Combine and Serve

1. Mix the Sauce and Pasta:

   • Pour the prepared spaghetti sauce over the cooked noodles. Gently toss to coat the noodles evenly with the sauce.

2. Serve:

   • Divide the pasta into bowls and serve hot. Optionally, garnish with grated Parmesan cheese or fresh parsley for extra flavor.
