Cook the pasta according to the package directions.
Sprinkle the chicken with seasoned salt and grill until done. Then slice it thin.
While the chicken and pasta cook, melt 3 Tbs. of the butter in a skillet over medium heat.
Add the onions and garlic and cook until soft.
Add the peppers and cook until they are tender-crisp.
Remove the veggies from the pan.
Add the last Tbs. butter. I accidentally let mine brown a bit, which tasted good. A happy accident.
Whisk in the chicken broth, then half & half.
Stir in the cheese.
Add 2 pinches of seasoned salt, about 1/2 tsp.
When the pasta is cooked and drained, pour the sauce into the pasta and combine.
Add the tomatoes. Serve with the chicken.
