Marinate the pork belly with minced garlic, salt, and pepper in a plastic bag. This step is optional.

Wash the salad greens and drain the water.

Boil spaghetti in salted water (1/2 tbsp salt, 1 tbsp olive oil) for 8 minutes.

While the spaghetti cooks, grill the pork belly in a heated pan. Cut into bite-sized pieces once cooked.

Sauté sliced onions in olive oil until slightly softened.

Add the prepared seasonings and 6 tbsp of pasta water to the onions. Stir well.

Add the cooked spaghetti to the pan and toss until the sauce coats the pasta evenly.
