One of my weekly staples is a "mighty bowl". It's easy to prep & can be ate hot or cold (so if you don't have access to a microwave or method to warm at work, it's still viable).
My bowl consists of:
Quinoa
Black Beans
Avocado
Salsa
Cilantro
Hemp Hearts
Feta Cheese
I cook up a big batch of quinoa & black beans 1 night per week. I chop a bunch of cilantro up & store it in the fridge as well.
Then I'll separate out everything else into mini serving 2oz containers w/ lids (I buy a bunch from Amazon --
http://www.amazon.com/Reditainer-Plastic-Disposable-Portion-100-Pack/dp/B009VSFZDO/ -- you might be able to find packs at the dollar store if you're too lazy to wait 2 days for shipping)
Then I put salsa, feta & hemp hearts into their own 2oz containers & am pretty much ready to go. If I'm feeling extra motivated, I'll serve out quinoa & black beans together into 5-7 containers (Again, Amazon is a great resource to make things easy --
http://www.amazon.com/Fitpacker-Meal-Prep-Containers-Microwavable/dp/B00VWJHFTM/ -- but you can use glassware of course, which is truly the "healthier" option) otherwise, I'll just madly serve out what I need each morning before I leave the house.
I also use the same containers (2oz & 16oz) for my salads. I make up a few "shred salads" (as I call them) each week.
Spinach
Cabbage (shredded)
Broccoli & Cauliflower
Dried Cranberries
DRESSING: olive oil, balsamic, honey, ginger, chia seeds.
These are the two easiest meals for me to prep. Both of them taste great too which is a big plus.
Tried to post pictures, but I think my post count is either too low or I'm blocked for some reason. :/
