An American classic. Create a vegetarian version by substituting ½ pound firm tofu, drained and crumbled, or Seasoned Tempeh Crumbles. Or, simply increase the amount of cooked rice to 2 cups. If the peppers are huge, you may halve them lengthwise through the stem instead (do not completely remove the stem, as it helps hold in the stuffing).
Position a rack in the center of the oven and preheat it to 375°F. Grease a baking dish in which the peppers will fit snugly. Prepare for stuffing:
If the peppers will not stand upright, level them by cutting a thin slice from the bottom trying not to create a hole. Steam the peppers on a rack or steamer basket over boiling water until tender, about 10 minutes. Set aside. Heat in a large skillet over medium heat:
Add and cook, stirring and breaking the beef up with a spoon, until it is lightly browned, about 10 minutes:
Remove from the heat and stir in:
Fill the peppers with the meat mixture and set them in the baking dish. Sprinkle over the tops:
Bake until the peppers are tender and the filling hot and firm, about 25 minutes. If desired, brown the tops under the broiler.
