One chart shows how it may finally be a better deal to buy groceries and cook at home again

• The price of groceries is rising much slower than dining at a sit-down restaurant or fast food joint.
• Grocery inflation has slowed way down: just over 2% year-over-year, compared to fast food at 6.2%.
• Fast food is not cheap anymore, as many major chains are hiking prices this year.

Over the last few months, it's become clearer that buying groceries and cooking at home may once again be a better deal than eating out.
