Hi Estrella
You just have to go back to basics and cook everything from scratch here. SW friendly instant meals etc don't exist.
I just use Mercadona mince all the time, dry fry it carefully and add a couple of syns to the meal.
You can live without frylight - just use ordinary Olive oil but only 1 teaspoon full at a time and you'll be fine. Tastes much better and much cheaper too.
Re snacks. You can get various muesli or rice type bars in Mercadona that are only about 80 cals a bar so I do a "fudge" and count these as a half HexB. I compared them them to Alpen lights and the fibre, salts, sugars, fats etc weren't that different.
You can get light cheese triangles in Mercadona too - actually slightly lower in cals that Laughing Cow lights so I substitute these. You can get the real thing and BabyBel lights in Carrefour. You can also get Philly light in Mercadona.
It is possible to lose in Spain - it just might be a bit slower. I've managed over 5 stone!! And if I can, anyone can.
Good luck chica.
