I can and have made them myself. Frankly, they are tedious and you need to make large batches to justify the work.
Stuffed peppers are not the same thing, but the flavors are very similar and just as comforting. I do not pretend to offer an authentic spice blend in this recipe. Very few Lebanese cooks, home or commercial, will tell all. The internet has cabbage rolls, of course. Even Martha Stewart has posted one.
When you read those recipes, you find there are as many different ones as there are regions. Some that look tasty call for things like 7 spice. When I looked that up, I found a startling diverse set of recipes for the spice. I gave up. Instead I have reverse engineered a spice blend. The proportion on the spices can and should be adjusted by you to suit your own taste, as should the amount you use in the meat.
This recipe is based on 4 to 6 large bell peppers. Figure 1 or 2 halves per person depending on the size of the peppers.
