Hi Edith,
My meal planning needs lots of work as I'm not very adept in the kitchen. But so far here's a sample of what I've been doing for the past 5 weeks.
Breakfast A protein shake made with skim or 1% milk, protein powder and flax oil. Or I will have an egg (boiled or scrambled) Orange juice and toast on whole wheat.
Lunch is either salads, lettuce or a tuna salad (sometimes I take the albacore tuna and put it with chopped apple, grapes, fat free mayo, celery and chopped pecans.) I love peanut butter, so I might have peanut butter on whole wheat. Sometimes I will have a chicken stir fry for lunch. Stir fry helps me to get more vegetables in.
A piece of fruit for dessert.
Snack at mid-afternoon is either a cliff or Balance bar, or low fat cottage cheese. If I didn't have a protein shake for breakfast, I may make a smoothie with yogurt, protein powder and flax oil and or fruit.
I personally need things that go crunch

so I have celery, and carrots available. For the salty crunch, I have low fat pretzels.
Dinner is either stir fry chicken, baked fish with a sweet potato with just margaine, pepper and cinnamon, a salad and fruit.
My favorite stir fry recipe is to cut up portions of chicken breast and brown it in about 1T of canola or olive oil. Put in chopped zucchini, yellow squash, mushrooms, onions, green and red pepper, broccoli and cauliflower and steam until done.
When vegetables are done, I pour in my sauce which consists of 1/4 cup of Kikomans low sodium soy sauce, 2T Cooking sherry, 2T cornstarch, 1tsp ground ginger, 1tsp sugar, 1/8 tsp of ground red pepper, about 1/4 cup of water. I cook this with the chicken and vegetables until thickened. Then serve over rice.
(some may want the sauce to be a little sweeter)
For a snack later on I may have cottage cheese, yogurt or low fat cheese on whole wheat crackers.
Throughout the day I have lots and lots of water.
This is quite a break through for me as I lived at the fast food eateries. I had tons of hamburgers, pizzas and at home thinking I was eating healthy, lots of baked potatoes. Cutting drastically down on these starches and red meat has amazed me in that I haven't missed it.
This is probably longer than you asked for.
Hope this gives you some ideas though.
