I save money and eat healthy by slow cooking large amounts of brown rice or beans and then saving meal sized portions in re-usable freezer and microwave safe containers. I also do this with chicken breast I use for salads and sandwiches and it saves me from buying the salty prepared kind.
I'm sure this has been posted a million times, but: there is nothing rice can't be added to to create more of a meal. Can of soup + rice = meal! Can of beans + rice = meal! Chicken broth + rice = meal! Lentils + rice = meal! Potatoes + rice = meal! Frozen, fresh or canned veggies + rice = meal! I could go on and on. You get the idea. Rice is a lifesaver.
Do you have a nice, low calorie recipe for a stew, chili, saucy dish, or topping, but find that once you add in the obligatory noodles or rice for it to sit on, its now way more calories than you wanted? Instead of pasta, try spinach. Instead of rice, try cauliflower rice!
Brown ground beef, drain the fat, then rinse beef with hot water (use a mesh collander; see one of my other tips). (Using hot water congeals the fat, and it won't rinse out through the collandar.)
