Go with the Grain
For an indulgent side dish, grab a bag of Arborio rice (for risotto), corn meal (polenta), or pearled barley. The dried, bagged stuff will cost less than $1 for a portion that can feed eight. Rehydrate with sautéed chopped onions and garlic, and bouillon cubes dissolved in water instead of expensive canned stocks. If you want to fancy-up with chopped fresh herbs or tomatoes, go for it; your total will still be under $4 for the entire dish.

Serve Salad After Dinner
It feels posh and good timing doesn’t cost a thing. Pick up a box of organic arugula for $3.99, which is more than enough for six. Toss with sunflower seeds or chopped nuts, sundried tomatoes or dried currants, and a few shavings or Parmesan or crumbled blue cheese (go with what you have; this is an opportunity to clean out the pantry).  Drizzle with olive oil and vinegar or lemon juice, and season well.

Dessert Is A Must
People tend to say no to formal dessert, but seek a little something sweet. So forego the pricey, time consuming and caloric cakes and pies and ask your friends to bring some gourmet chocolate (a little goes a long way). Pair the chocolate with strawberries, blueberries or even clementines. Since seasonal fruit tastes best, and is always less expensive, you’ll be able to find a sweet ending in the produce aisle for less than $5.
