There are a few kitchen hacks that can help you. One of the simplest is to simply brine your chicken. The chicken you get there tends to be tender and juicy, and you can achieve that by letting your chicken soak in a salt/salt and seasoning bath which keeps moisture in the chicken as it cooks, adds flavor deep into the chicken, and tenderizes it.
also, be sure to heavily salt your water when boiling noodles. the salt helps to prevent them from sticking together and it boosts their flavor.
and while I'm on the subject of salt. add it to any vegetables that you are trying to caramelize down, like onion and carrot, very early in the cooking process. the salt draws out the internal moisture which means that the vegetables will caramelize instead of steam.
If you follow these you will need to add little, if any, salt at the end of cooking.
Also, use the freshest, most whole ingredients that you have. quality does matter for many things, but especially for oils, for pasta, and for tomatoes.
you can look up copycat recipes of olive garden meals, with the chicken gnocchi soup being an easy one to try out first. olive garden isn't "real" Italian food, but it is tasty.
