The American Heart Association's Quick and Easy Meals cookbook (
http://www.amazon.com/American-Heart...e=UTF8&s=books) is a great source of easy peasy meals. And it includes nutritional info for every recipe, so you won't need to figure out the calories on your own as long as you follow the recipe (you can vary the spices if you want, which don't usually impact the nutritional content).
Breakfast can be very easy. I eat the same high fiber cereal with soy milk every day. Finding a low calorie but nutritious cereal (there are lots out there) that you like would be much better for you than eating a frozen meal and just as easy (and probably more satisfying).
Lunch can also be easy. PB&J sandwiches were a staple for me for a long time. I've now branched out to turkey and ham sandwiches. I also make some other more creative lunches, but I eat sandwiches once or twice a week (and I always have a PB&J on Sundays---mmmmmm, peanut butter!!).
I do eat lean cuisine and weight watchers entries from time to time, usually for lunch when I am pressed for time, but not very often. I am convinced that they have more sugar and fat than food I make myself and that they get the calories down mainly by reducing the portion size. I find that I can eat a lot more food for the same calories when I make it myself. I also find that I get hungry again quicker when I eat the frozen entries. And then there is all that sodium and the lack of nutrients. Oh and the taste.

Years ago I ate frozen entries every day for lunch and it got to the point where I just couldn't stomach them any more (and this is unusual for me, normally I can eat the same thing over and over again and never get tired of it). They just don't taste as good as food I make myself. I think that if you eat them everyday, you are going to get tired of them very quickly.
And I agree with the others that 1250 calories per day sounds way too low for you. I am a woman, 5' 3", weighed 150 when I started my diet, and 1200 calories was my limit when I started. I lost 1.5 to 2 pounds per week at that level. Since you are a man, taller, and well-built, you clearly should be eating more calories than I started at. Add a little exercise and you'll need to eat even more. I now weigh 118 and 1200 calories would way too few even for me because of the amount of exercise I get.
To lose weight, you should eat 500 calories less than the number of calories you would need to eat to maintain your weight. So if it is recommended that you eat 2500 calories to maintain your weight, then you should lose weight at a reasonable and safe rate at 2000 calories per day. This is more of an art than a science, so you might need to adjust the numbers a bit, but 2000 is probably a good starting point. If after several weeks, you aren't losing weight at that level, you can try dropping your consumption down by 100 calories every couple of weeks until you start losing.
