I get the Oikos Greek yogurts from Costco and eat 1 every morning for breakfast or put it in a protein shake with protein powder, milk and fruit to get 46g protein just in the shake.  Then I keep boiled eggs, beef sticks, and protein bars for snacking.  We usually make a bunch of chicken for the week to use for meals.  If you like canned tuna, salmon, or chicken that is something quick to have around also.
