Stand pepper upright. Slice straight down along the sides to remove the “panels”. Rotate and continue slicing each side or panel off (you’ll have 4 sections now).
Method 3: Cut off a little of the bell pepper from the top and bottom. Discard the stem from the top and slice down one side vertically so you split the bell pepper open.
Open/“unroll” the pepper. Slide the knife inside the pepper and run it round the interior, separating the pepper from the ribs of white pith. This will detach the seed cluster from the flesh in one piece, almost always with no mess. Discard seeds.
