There are so many different things you can try to make your mac and cheese customized to your family. If you’re vegetarian, you can omit the bacon and use roasted broccoli instead. That’d be delicious! (On the other hand, if you want some more veggie content but you’re not vegetarian, keep the bacon and add the broccoli anyway!) You could also omit the bacon and add veggie sausage in its place, but the easiest way to alter this recipe is to omit the bacon entirely and enjoy the creamy mac and cheese on its own.
