We made 1/2 recipe onions and cooked a whole flank steak so there are leftovers. Since it was so hot out, we broiled it in the oven. The recipe suggests 8 minutes a side, we like it medium rare so cooked it 4 minutes a side and it was perfect. I was sceptical of the onions, but followed the recipe and it worked perfectly. The sweet onions compliment the spicey rub. I used 1 Tbsp. of pepper and it was just right. Served on burger buns with a green salad and veggie chips. Will definitely make it again, would be good for company.
