Cook pasta according to the instructions on the package and strain it, making sure not to exceed 10 minutes.
Heat oil in a medium-sized pot over medium heat.
Add chopped green onions and garlic to the pot, stirring them until they are fragrant.
Add jerk seasoning to the pot and stir for about 2 minutes to ensure that the onions are coated.
Pour in milk and mix well, taking care not to burn the mixture. You can also place bell peppers (coated in olive oil, salt, and black pepper) in the oven for approximately 15 minutes at this time.
Add half of the cooked pasta to the pot with the milk mixture.
Add half of the Parma Rosa powder to the pasta and mix well.
Add half of the cheese and stir until it is fully incorporated.
Add the remaining Parma Rosa powder and cheese, ensuring that all clumps are dissolved.
If using meat (chicken or shrimp), add it to the dish at this point.
Add the roasted bell peppers, remaining pasta, and a little more milk if all the liquid has evaporated.
Remove from heat and serve.
