6113 -  Rise a Shailah

A. Mishna Berura (639: 13) rules that eating many fruits, meat, fish, or anything that isn't made from the five kinds of grain, does not require a suka. However, Poskim maintain that if it is considered a main meal, one should make an effort and eat in the suka without the brocho on the suka. (See Piskei Teshuvos ibid 9, Nitei Gavriel and others)

Horav Shlomo Miller's Shlit'a opinion is similar.
