To those asking what else to purchase when they go grocery shopping, I noticed you guys didn't mention/picture any produce. Broccoli, Cauliflower, Kale, Spinach, Asparagus, Quinoa, lettuce, etc...can all add variety and flare to meals without adding tons of calories. Plus these items pack nutrients which aide in your immune and digestive systems as well.
I'm no expert, but Spinach, Kale, and Mushroom omelettes have been a nice breakfast item for me. Sautee the Kale, Mushrooms, and Spinach in Coconut Oil and seasoning (like the kind DC posted awhile back) and then add your eggs/egg whites. Simple, but effective.
Another solid meal I've had fun with is ground turkey stuffed bell peppers. Essentially the same mixture used in making a meatloaf, but now stuffing 10-12 bell peppers. I've done it twice...first time I criss crossed Turkey Bacon strips over each bell peper before baking them...damn that was good.
Also, you could pickup a few cans of tuna (in water preferably) for those times you want a healthy snack. The pouches work pretty well too.
Just a few ideas from items which have worked well for me.
