Consumers are eating sandwiches more often and picking up more sandwiches away from home than they did two years ago, according to “The Sandwich Consumer Trend Report,” published in mid-May by market research firm Technomic.

The data, based on Technomic’s MenuMonitor database, found 43% of consumers said they eat at least four sandwiches each week, up from 39% of consumers in 2010. Additionally, consumers noted 49% of the sandwiches they ate were purchased at restaurants or other food service locations, up from 44% in 2010.

Technomic said the improvement in the economy has played a role in the increase, but so has the continued growth of breakfast sandwiches in the limited-service restaurant (L.S.R.) segment. Over the past two years, the MenuMonitor data showed sandwich entrees have increased 35% on breakfast menus at the top 500 L.S.R.s, and more chains (60) offered breakfast sandwiches in 2011 than in 2009 (53).

“The significant increase in breakfast sandwich offerings points to how L.S.R. operators are promoting convenience and affordability attributes to target morning consumers,” Technomic says.

Tortillas were identified as the leading type of sandwich bread on L.S.R. menus, according to the report. Meanwhile, buns, ciabatta and sourdough bread “have made a slight push” on L.S.R. menus since 2009, the study showed.

Similar trends were noted at full-service restaurants, where tortillas appeared on 8.4% of sandwich menu descriptions in 2011, up from 5.1% in 2009. Both tortillas and buns have passed sourdough as the leading types of sandwich bread on F.S.R. menus since 2009, the report said.

Looking at sandwich preferences for all dayparts, bagels and croissants stood out as the top choices for breakfast sandwiches, with 45% of those surveyed saying they likely would order a croissant and 44% saying they likely would order a bagel. Thirty-six per cent said they were likely to order biscuits or English muffins, while 33% said whole wheat/whole grain bread would be their choice. Twenty-four per cent said they most likely would order a tortilla/wrap for breakfast.

Italian, French and whole wheat bread were the most preferred varieties for sandwiches eaten at lunch and dinner.

“Each of these breads is versatile and can be used for a wide range of sandwich varieties,” Technomic says. “Some differences in bread preferences were observed by daypart. Flatbread and tortilla are more likely to be ordered at dinner than at lunch, likely due to the larger wraps offered at full-service restaurants.”

More than half of consumers surveyed by Technomic said they eat sandwiches for lunch once a week or more often, while about 40% said they eat sandwiches for dinner at least once a week, and more than a third do so for breakfast.

But an untapped market may be marketing sandwiches as snacks, Technomic said.

“A quarter of consumers surveyed say they never eat sandwiches as a snack,” the report noted. “Offering smaller-portion sandwiches at lower price points that can be eaten on the go — such as wraps or mini-sandwiches — may help to boost sales of sandwiches as a snack.”
