Heat a pan with olive oil. Then add the chopped garlic.
Once it smells, add the cubed chicken pieces and saute for few minutes.
Put a lid on and cook for few minutes till the chicken is soft.
Then add the chopped bell peppers, salt and herbs.
Cook till done and add the boiled pasta and stir. Keep aside.
To make the white sauce, heat a nonstick pan with butter, and add the flour.
Keep stirring till it is cooked which takes about 3-4 minutes.
Slowly add the milk while stirring, so that there are no lumps. Add the salt and pepper.
As soon as the sauce thickens, switch off the flame.
Now mix in the Cheddar cheese and stir followed by the cooked pasta.
Serve it with a generous sprinkle of grated Parmesan cheese on top.
