There's nothing like homemade bubbly, creamy macaroni and cheese. Ditch the store-bought stuff and make your own. It's much easier than you think and tastes a million times better.
In a medium saucepan, cover the noodles with water and bring to a boil.
Turn heat down to low and simmer until the noodles are done to your liking. (with rice pasta, it is better to have them more on the al dente side because they can quickly turn to mush).
Drain in a colander and rinse the noodles (rice noodles can get slimy and need to be rinsed).
Put noodles back into the saucepan and put on low heat.
