A very common snack eaten by Libyans is known as ''khubs bi' tun'', literally meaning "bread with tuna fish", usually served as a baked baguette or pita bread stuffed with tuna fish that has been mixed with harissa (chili sauce) and olive oil. Many snack vendors prepare these sandwiches and they can be found all over Libya. Libyan restaurants may serve international cuisine, or may serve simpler fare such as lamb, chicken, vegetable stew, potatoes and macaroni. Due to severe lack of infrastructure, many under-developed areas and small towns do not have restaurants and instead food stores may be the only source to obtain food products. Alcohol consumption is illegal in the entire country.
