Slice a strip lengthwise from the zucchini to expose the inside of the vegetable. Discard or reserve for another use. Cut the 2 ends from the zucchini to make straight edges. Cut the zucchini lengthwise into ¼-inch strips (10 pieces).
Brush both sides of the zucchini pieces with olive oil. Season with salt and pepper.
Lay the zucchini pieces on the grill. Cook until the zucchini is very tender, but not mushy, 2 to 3 minutes per side.
Remove the zucchini from the grill and set on a cutting board.
Spread 2 teaspoons of hummus on each zucchini slice. Divide the red pepper evenly amongst the zucchini.
