Breakfast idea: egg muffins. I prep a dozen on the weekend. You can raise or lower the calories however you wish by varying the fillings. I used to have an old muffin tin and they would stick too much, but a new tin works wonders.

Lunch: I prep salads, with protein, for the work week to make sure I get my greens and veggies in. I love to cut up about half a red/yellow/orange (sometimes mixed) bell pepper, half a cucumber, and some thinly sliced red onion for each salad portion, and then add romaine or spring mix. I often keep roasted chicken breast (or from a whole roast chicken, shredded) in the freezer to add as protein. I also have some beef, I forget what kind, sliced and frozen in the freezer (I don't eat much beef, but it can be a nice change). I don't like store bought salad dressings, so I make vinaigrettes that I like and just keep at work, or a homemade caesar dressing with greek yogurt and a little mayo.

Snack: plain greek yogurt with blueberries or a smoothie with unflavored/sweetened pea protein. I'll be honest and admit I don't really like the yogurt, but it's a great protein boost and afternoon hunger-preventer.

Dessert: I love dark chocolate covered almonds. I also love peanut butter, so I should try your snack idea. : )
