Speaking as someone who cooks, a typical pantry should last you at least 2 weeks if you just wanted to survive. Flour, pasta, rice, eggs, various preserved meats and vegetables. Anything you have that is perishable could probably be immediately preserved and will easily last 2 weeks. If there was really a problem, my main concerns would be water and power.
