Cook the spaghetti first. Use the instructions on the package, and don't overcook the pasta. When draining it, make sure to set aside 1 cup of pasta water.
To start the pasta sauce, heat some olive oil in a large frying pan over medium-high heat.
Add the Dominican salami and leave it to fry until it becomes brown on both sides (roughly 3 minutes per side).
Once the salami is cooked, lower the heat to medium and add the diced red onion and garlic. Stir the ingredients well and leave them to saute for about 3 minutes.
Add the red and green pepper and stir them in. Leave them to sweat for 2-3 minutes.
Next, you can add the seasoning ingredients. They include the sofrito, Adobo, Sazon, and Dominican oregano. Stir them in well while they sweat for a minute.
Then, add the tomato sauce and mix so all the ingredients are uniformly distributed. Leave the Dominican pasta sauce to cook for about 5-8 minutes.
Season the sauce with black pepper and sea salt to your liking.
Now, if your sauce is too runny, you can add a little bit of the pasta water and bring it to a simmer. The starch in the water helps make the sauce thicker.
Finally, stir in your cooked, drained spaghetti noodles and serve this pasta while it's still warm.
