Cook Pasta: Pour water in a shallow saucepan or pot and bring to a boil. Add salt then add pasta and cook (two minutes less) according to the package instruction. If the instruction says to cook for 8 minutes you will cook for 6 minutes.

 Add a dash of oil so it doesn't stick together. Drain and set aside make sure you reserve about half a cup the pasta water. 

In a large saucepan, over a medium-high heat. Saute the garlic and chopped onion. Add the chopped bell peppers ( the bell peppers are optional, I used them to give some colors) and cook for about one minute.

Add the sliced mushroom and stir. Continue to cook and until the liquid released evaporated about 6 minutes. Add salt and seasoning cube.

Add the cooked pasta and about 1/4 cup of pasta water and combine until the pasta is coated with the sauce. 

Cook until the water thickens, take it off the heat if you like cheese garnish with some parmesan cheese.

Serve.

Enjoy!
