You can easily cut a bell pepper in a couple steps. Step 1: Slice off the top of the pepper to remove the stem. Step 2: Cut the pepper in half, longways. Step 3: Carefully cut or scoop away the fibrous innards of the pepper. Remove the seeds as well. Rinse the inside and outside of the pepper to remove any stubborn seeds. Step 4: Lay the pepper with the inside up and cut it into slices. You can then dice the slices if you want diced pepper.
