Cooking healthfully means getting plenty of fruits and vegetables in your diet and most people don't get enough! Aim for 4 to 13 servings a day. A serving size is 1/2 to 1 cup depending on the fruit or vegetable. We know that not everyone is a fan of this principle, so that's why we like recipes like Hamburger Buddy. Very finely chopping onion, mushrooms and carrots in the food processor is not only fast-it makes the vegetables hard to detect for picky eaters. They also form the base for the sauce of this ground beef skillet supper. Enjoy!
