Wash and dry the spinach leaves, place some leaves in an aluminium foil dish or oven pan. sprinkle some spices on one layer. place the beef in between and season then cover with another layer of spinach and season. cover tightly and put in the oven for about 40 minutes at 180c and check after 30 minutes. done :) no oil or water required as the meat and spinach naturally produce jucies.
This is how it looks like at the end.
Update on HCG drops diet, although they were amazing for both rounds I had to stop using them. I got breast pains every time I tried but it was nothing serious, so be careful that by time your body might not accept it.
