I hear the same thing day after day "The price of gas is eating into my
grocery budget!"  It is very hard right now to choose the organic
product that is twice the price of the non-organic, or the burgers and
hot dogs over the lean chicken and pork.  It doesn't take a lot of
effort to keep your meals high quality while still filling your tank,
just a little creativity.

Obviously, you're already planning with the sale flyers.  But try to
think lower on the food chain.  Get your family to eat at least one

bean meal a week. It could be something as simple as Baja Black Beans and Rice. 
This is good on its own, and equally as good as a burrito or fajita
extender.  Grilling sandwiches is a great way to elevate a cheap meal
into something special.  Just let everyone make their own sandwiches,
and then grill them open faced.  Add the cold toppings like lettuce and
tomato after the sandwiches are grilled.  Grilled pineapple slices or
peaches make an excellent dessert.

Thankfully summer is coming so instead of expensive jars of organic
pasta sauce you can dress your pasta simply with olive oil, herbs, and
lightly steamed vegetables.  Try to get in the habit of drawing off a
cup of the pasta water before you drain the pasta.  It's an easy way to
stretch your sauce without adding extra oil.  Make a large salad and
offer a variety of toppings like hard boiled eggs, cheeses, and
olives.  Most leftover salad toppings can be folded into an omelet or
chicken/tuna salad the next day.

Think about cutting back on the entree and adding an extra vegetable or
fruit.  The more choices there are to put on a plate, the less that the
big hunk of meat will be missed.  It's much healthier than adding an
extra scoop of rice or slice of bread, too.

To save money, add variety, keep it simple, and keep it fresh.
