If you have a Trader Joe’s near you, look for their grilled artichoke hearts. They come in a box, and they live in the dry-foods aisle (as opposed to the refrigerator aisle). They are delicious. They are on the small side, so I don’t bother cutting them, though I do drain the oil. Once I made this and used the entire package, oil and all, and the flavor was a little overpowering and slightly artificial as well. If the artichokes you are using are on the large side, halve or quarter them.
