Most of the online resources will lay out the calories, etc of the recipes. If you want to cut from that, then use the lower fat options, etc.
I like allrecipes.com and foodnetwork.com to name a couple.
Get basic books if you are into cooking... they have easier to follow directions, etc. Then, gradually step it up...
I love to cook and I cook often. We love baked potatoes, steamed veggies, lots of fruits, we eat a lot of steaks which are all purchased from our butcher and is top quality... I never, ever purchase beef in the grocery store. Get some spices you enjoy... fresh basil is wonderful! Experiment with different tastes and textures.
I realize you are trying to lose weight... keep in mind to eat in moderation. You don't need to go ALL fat free, etc... your body needs some fat... just in moderation. Exercise as well... walk the babies, play in the park, simply be active with them at home.
If you have any favorite foods and don't know a good recipe, google or PM me... I have a few favorites around here and you just might like one.
Good luck...
