After the meeting, we’re scheduling lunch at a restaurant that has a great sashimi bento box.
Slash somebody, take their flesh, then eat it raw. This kind of food is known as sashimi, yum!
The reading is a little weird. It's double kun'yomi where the 刺す becomes stem form and gets pushed inside the kanji to become さし. The 身 is just the word 身's reading.
