I end up eating at work a LOT. I bring things like: a big bowl of cut up veggies, yogurt, soup, meat and cheese roll ups, fruit, and reduced fat cheese sticks. I also do a lot of leftovers.
At home, the kitchen is your best friend. Stock your fridge with fresh, healthy food. Don't force yourself to eat anything you don't like, but try all sorts of new things. It's amazing what foods are out there I thought I wouldn't like or never knew existed. Weigh and measure everything at first so you know exactly what you're getting and track everything with your food tracker so you have a good record. Plan your meals: To start out with pick a protein: let's say 3 oz of chicken breast (maybe cook that with tomato and onion). Next pick a starch: let's say rice ( now add all sorts of chopped veggies so that your 1/2 cup of rice is now 1 1/2 or 2 cups of food). Now add a Veggie (not spinach!) or a side salad. There are tons of great soups and casseroles too, but it's easier to start by visualizing everything apart.

Have fun and eat well!
