Chips and dip are fine, but what's a party without fancy little finger foods? The devil is in the details, of course--it's time consuming and expensive to whip up gourmet treats for your guests. Trader Joe's, however, lets us put on a swanky soiree without breaking either our backs or our bankbooks. There are myriad premade tasty treats like marinated mozzarella braids, Thai shrimp goyoza, and colossal olives stuffed with garlic or jalapeņos. All are ready to roll: no cooking, just arrange on a platter and pass the cocktail napkins as your guests marvel at your elegant self-catered spread. For the final touch of class, check out TJ's unbelievably inexpensive caviar--to go with those champagne crackers we get to serve, even on our beer budget.
