Here are some quick lunch ideas.. (these all take under 10 mins and VERY little effort in the kitchen..no watching over them)
pre-make some primal mayo for the week..
Open a few cans of tuna, throw mayo and spices on top
Hard boil some eggs (you can get a nice device that times it for you), top with mayo, spices, and cooked veggies
Throw some meat right in the crock pot the night before with some spices (double or triple portion)
Take chicken breast with skin, put skin side down..throw in the oven with olive oil onion powder/garlic powder/ or whatever else you like.. cook for 30 min
You can buy bags of veggies that you just have to throw in the microwave to cook, both fresh and frozen
you can buy pre-cut veggies, or just cut up a few servings worth 2 nights a week, then throw them together in a salad or bring the ingredients with you and cut them up at work.. then throw the crock pot chicken on top, or the hard boiled eggs in it, or the tuna on top
Or you can take that crock pot meat and just grab a bag of frozen veggies, and heat the veggies up at work throw the juices on top with the meat, and boom nice warm meal
Or make a large pot of soup on Sunday and have it for 2-3 days.
