The first thing to do is cut off 1/2 inch from the bottom of the pepper and another 1/2 inch from the stem end. Remove the core by running the knife around the flesh, then lay the pepper on its side and slice the skin side down into rings or strips. You can also dice it into whatever size pieces you want. Cut peppers can be cooked in a wide variety of ways and added to dishes like omelets, pilafs, stir-fries, and more.
