Successes are easy. Let’s talk about the failures.

For her second cookbook, co-written with Deanna Segrave-Daly, Serena Ball had an unusual idea. She was developing a recipe for Beef and Quinoa Koftas — Middle-Eastern meatballs — and she thought she could add nutritional value and moisture by mixing in some chopped prunes.

The idea makes sense on paper. But when she sent the recipe to a tester, the answer came back a big, fat NO. The tester said she doesn’t like prunes. They’re weird, she said. So the prunes came out of the recipe.

The book was released last week. It is called “Easy Everyday Mediterranean Diet Cookbook,” and the title exactly describes the authors’ focus.

“We wanted people to understand that you can definitely do the Mediterranean diet — buy foods in regular grocery stores, have a pantry list that is budget-friendly and have a way to cook that is quick,” said Ball, a dietitian who lives outside of Hamel, Ill..

The Mediterranean diet begins with foods that are commonly eaten around the Mediterranean Sea, but it is also about a certain lifestyle, Ball said.

“It’s more about slowing down, enjoying your food, eating with family and friends. ... The foods tend to be more seasonal, and you tend to waste less food, too,” she said.

The diet emphasizes fruits and vegetables, whole grains, beans and lentils. Fish and meat are also included, but in smaller amounts. Nutrient-dense olives and olive oil are a part of the diet, and so even is pasta.

“You don’t have to worry about eating pasta,” Ball said. “One of the coolest things about white pasta is that if you cook it properly, if you cook it al dente so it is firm and toothsome, it is not high-glycemic.”

Ball and Segrave-Daly use foods from the Mediterranean area — primarily the northern and eastern parts of the region — as a starting point, but they adjust the flavors to fit the American palate. They add bacon to their version of the Lebanese salad Fattoush, for example, and include salmon in several recipes when salmon is not found in the region.

One of the salmon recipes uses salmon from a can, and that is another of their strategies. The book is geared toward convenience, making full use of frozen fruit and vegetables, canned tomatoes and instant rice.

The idea was to create weeknight recipes that could be made in 30 minutes. Their previous book was called “30-Minute Mediterranean Diet,” and Ball said, “we can’t have two books with the same name.”

While much Mediterranean cooking is done over a grill, Ball and Segrave-Daly have developed a couple of hacks to re-create the flavor of grilled food in less time and trouble. They broil many dishes that would otherwise be grilled and add smoked paprika to others, which adds a natural taste of smoke.
