Can I re-heat?

Of course, make in a bulk and freeze some for some other time.

It will keep in the cooler for a couple of days and it makes extraordinary extras to prepare in your lunch the following day.

Can I add other vegetables?

Absolutely, diced baby carrots go well admirably, or do try cut mushrooms (which are supplemented by the cream of mushroom soup!).

For the sake of your ease, you can likewise utilize a variety of mixed vegetables.

What can I add instead of milk?

Of course, you can utilize heavy cream or creamer instead of milk for a creamier surface and more extravagant flavor (but hey! be careful the fat calories) 😉

What can I add instead of Tuna?

Well, it's a tuna recipe but if you want to try something else you can go with Canned chicken or salmon.

What can I add for toppings?

You can add crushed potato chips on the top just to have some toppings.

What can I use other than Mozzarella Cheese?  

Well, you can opt for your favorite one.

Otherwise, try using cheddar or parmesan cheese.

Is there any substitute for Penne pasta?

Yes, you can use any type of pasta you like.

If you want to try something different then you can also go with egg noodles instead of any pasta.
