AllWhites® Egg Whites and Better'n Eggs® Home
My husband and I carry these around with us. Put em in a cooler and just drink. I drink 10 ounces 3 times a day. I drink them plain and he likes to mix crystal light in for flavor. This has really helped us gain lean muscle and it's cheap!
If you have access to a costco membership, sam's club or even if your local grocer stocks the roasted whole chickens for around $5, that's a great meal for the work day.
Try liquid egg white, put splenda and cinnamon for flavor.
