Peel 2 medium onions, and cut a thin slice from bottom and top of each one. Scoop out a 1-inch-deep hole from the top of each onion. Place onions, top sides up, in a 2-qt. microwave-safe dish with a lid. Add 1 beef bouillon cube and 1/2 Tbsp. butter to shallow hole in each onion; cover with lid. Microwave, covered, at HIGH for 8 to 10 minutes or until onion is tender. Garnish each serving with fresh parsley sprig and pepper, if desired.
We recommend only Vidalia or Texas Sweets for this recipe.
Be sure to use a microwave-safe lid only; plastic wrap will melt.
If you'd rather grill, wrap each filled-and-topped onion in heavy-duty aluminum foil (or a double layer of regular aluminum foil). Grill over high heat (400° to 450°) 15 to 20 minutes or until tender. Let stand 10 minutes.
