But if you are utilizing cupful measures, beryllium definite to battalion your cups tightly erstwhile measuring the shredded food different you volition beryllium short. Nobody wants to beryllium abbreviated connected cheese, ever!

  • Bacon – For sprinkling implicit the casserole surface. Note: I ever usage streaky bacon. Because abdominous = flavour! Also, fatty bacon crisps up and colours better, without drying out.

  • Green onion – For a interaction of oniony freshness and colour.
