Another great way to save time in the kitchen is to pre-cook yoru protein for the week. A BBQ grill is great for this, as you can prepare a big batch of chicken breasts, turkey sausage, burgers, etc. on the day you go grocery shopping (perhaps while your chopping veggies) and refrigerate them until you need them. You can then simply heat them in a pan or in the microwave in a snap whenever you're in need of a quick meal or even to sit down for a meal with the family!
Vegetarian? You may also use alternative protein sources such as dairy products (Greek yogurts, plain yogurt, low-fat cheeses, skim milk, etc.), soy products (tofu, tempeh, soy burgers, soy jerky, soy sausage, soy bacon, seitan, etc.), or supplemental protein (whey, casein, or milk protein blends).
