If you like cooking (or eating), I recommend [cached]Serious Eats. They have many great recipes that are easy to follow as well as delicious - for most of the new dishes I've tried recently, I've followed recipes from Serious Eats.
Two of my favorite dishes for a lazy day are [cached]Gyudon, a simple rice bowl heaped with beef and onion simmered in a mix of soy sauce, sake and dashi:
