that help me stay consistent with my nutrition. 
1. i cook a grain in bulk.  right now i am sticking with quinoa.  you could do brown rice, whole wheat pasta, barley, bulgur, farro, millet, couscous.....just make sure it is a WHOLE grain!  i like to cook it in a broth to increase the flavor!
2. i make a pesto.  this can be done with pretty much any fresh green herb or dark leafy green, nuts or seeds, and oil.  that is the base.  then you add flavor with garlic, lemon, salt/pepper, and parmesan cheese.  today i did basil and mint, toasted almonds, lemon, garlic, salt/pepper, parm, and olive oil.  put everything in the food processor and pulse, then stream in the oil while it is on low.  this makes a paste that you can add to your grain!  experiment with different herbs and nuts/seeds to see what you prefer.  cilantro, arugula, parsley are also good, as well as pine nuts, walnuts, pumpkin seeds (without the shell), and sesame seeds.  this adds so much flavor and nutrients to your plate!
3. i roast a big piece of fish.  i love wild caught salmon, so i have been sticking with that for the past few months.  best way to roast = coat with olive oil, salt and pepper and bake at 300 for 30 minutes.  this is for a 1.25-1.5 pound piece.
so, 3-4 days during the week, my lunch is about 1/2 cup grain topped with 1oz pesto and 3oz fish + a fruit and veggie.
4. ryan makes a bunch of protein pancake batter to use for the week for breakfast.  one serving = 4 egg whites, 1/4 cup cottage cheese, 1/2 cup oats, and flavorings (cinnamon, vanilla extract).  blend up and cook like pancake.  if make in bulk, just store in the fridge in airtight container.
this keeps us consistent with our meals and snacks during the day.  it also helps me focus on keeping the variety in for dinner.  since breakfast and lunch are taken care of, i can put a little more thought into my dinners! 

we also make sure we have fresh and dried fruit on hand as well as nuts and seeds.  we also keep lara bars in the house to bring with us to work.   also, always having baby carrots and hummus to munch on, which is a great way to get extra veggies in! 
if this sounds overwhelming, just focus on one thing at a time!!!
