Tips & Tricks
You can use whatever sort of pasta you like, you may just need to adjust cooking times accordingly.
You can also use [eafl id="25420" name="Al Dente Carba-Nada Egg Fettuccine, 10-Ounce Bags (Pack of 6)" text="carbanada noodles"] for a lower carb option.
If you would like to add other vegetables like bell peppers, etc. add them with the peas and carrots and do not stir those in, as they are quick cooking.
While not traditional, I do sometimes add a little grated parmesan cheese on top because cheese!
