a few ideas for you
Good for you on your decision to make changes happen to create better health! You'll want to build habits and strategies to incorporate foods that taste great and you can eat throughout your life. You can do a lot better than frozen diet foods.
Frozen diet meals are generally low in nutrients, fiber and - most importantly - flavor! They're also high in sodium and food additives no one can pronounce.
Pick up an expandable stainless veggie steamer - they have them in the kitchen gadgets isle of walmart or target - and you'll have a great tool to help keep you well fed. Use it to steam broccoli, snow peas pods, cauliflower, baby carrots, brussel sprouts, sugar snap peas - you name it - in just 5 minutes. It's a great time-saver and steaming retains nutrients.
You can sautee, pan-grill or bake a chicken breast or fish portion with a sprinkle of herbs from the cupboard, add a squeeze of citrus and serve it next to your steamed veggies to make a beautiful, healthy and yummy meal in no time.
Here are two good books for people wanting to learn new food habits:
365 Days of Healthy Eating from the American Dietetic Association (by Roberta Larson Duyff and the ADA) - which you can buy through Amazon.com for around $5 including shipping.
ADA's Complete Food and Nutrition Guide (by the same authors/editor as above) which can be had for around $15.
Best of luck!
