Buy a 2.5 - 3 quart size crock-pot/slo cooker and cut meat and veggies to fit the pot. Most grocers will cut your meat choice to size if you can shop in the morning. You can easily adjust any recipe for crockpot/slo cooking. Basically, remember to reduce the liquid to only one cup.
Cooking for yourself is a challenge due to quantities. Whatever you make, just portion out [one serving] into zip bags, label and stack in the freezer. In a short time you will have enough entrees in your fridge freezer to limit your need to cook only three days ea. week.
