Put time into dinner now, and you can make it last forever -- or at least the whole week. Welcome to Halfway to Dinner, where we show you how to stretch your staples every which way. 

Today: Kelsey of Happyolks merges eating well with eating on a budget, and she does it all with a sack of potatoes. 

After cooking potato after potato, I knew this post must be dedicated to my 21-year-old brother and his housemates. If there is anyone on this planet who would find a column dedicated to a week's worth of potatoes useful, it be would him. For Austin, who loves to cook and play and celebrate life, here is a week of meals for you and your friends so you can eat well, cheaply. 

Not sure which potato to pick at the market? We'll lead you through the different varieties and the best uses for each.

Inspiration for tonight's dinner: just good food. A steak, medium-rare please, and some tangy, goat cheesy mashed potatoes.
