To be honest the meals in our book are just that: aimed at the masses. The recipes on the website are where I have fun - so not for everyone.
Remember as well....you can always take a recipe and alter it to your liking - take out spices, not hot stuff, use chicken versus tuna, that kind of thing.
The key on calories is add in more - for example the mashed potato burritos do have good calorie counts (when you buy flour tortillas read the back, you will be shocked.) Two flour tortillas, 2 ounces of cheddar or cojack cheese, the mashers and yes, add oil or butter and you have a porky meal.
My advice is add fat when you can, eat breads to fill you up as needed (tortillas as mentioned or bagels) and add nuts to meals as well for more fat.
