Especially when you're just getting started, you can eat clean meals with a little help from the grocery store. Whole-grain crackers spread with nut butter or some cheese and a granola bar make for perfectly acceptable mini meals. You don't have to make everything from scratch.
Build your clean eating plan right into your daily routine. Eat breakfast within an hour of waking up. Then schedule a morning snack three hours later. Eat your lunch at the regular time. Then have a piece of fruit during a mid-afternoon break. Eat your dinner at the regular time, and have a snack a few hours later to help you wind down your day and get in the mood for bed.
You may want to start a journal of your favorite mini meals. Think of the snacks you enjoyed as a child and try to find ways to convert them into clean foods. For example, if you loved eating nacho chips with soda pop, try to make your own crackers with nuts and seeds, and enjoy a few of them with some iced tea sweetened with agave nectar. Before you know it, you'll have a long list of snacks and mini meals that you enjoy eating.
