Snack your way through dinner with these delicious small bites from all over the world. I start at the birthplace of appetizers for dinner – Catalonia, Spain. There I taste the famous jamon with a local chef, who teaches me two quick tapas – a Spanish omelet and simple Bread with Tomatoes. In Turkey, I taste local cheese in the bazaar, then join some Istanbul natives for Mushroom String Cheese Dip slathered on bread. I answer a viewer’s question about spices on “Ask Sara,” and finally, I make my own favorite snack, a decadent Alsatian Onion Pie with melty Gruyere cheese from the Alps.
