I'm terrible at lunch ideas and struggle with that, but here's some of the things we have for dinner.
Taco salads without the shell. Kids and hubby can have tortillas with theirs if they choose. Use lots of greens and beans. Leave out the fatty ground beef. Go easy on the cheese. Sub plan greek yogurt for sour cream. Did I mention lots of greens? Oh and tomatoes, onions, green peppers, or any other veggie you like. Here's an example with pics
Black bean patties. Kids and hubby can make theirs into a burger. You can too or leave off the bun for less calories. Add some roasted veggies or side salad to make it a meal. Here's my post
from making them a while back with details and photos for making Brit's Black Bean Burgers.
Grilled sandwiches - My husband loves these and they take next to no time to make. You make them just like you would a grilled cheese. Use a few sprays of butter spray instead of the large smear of regular butter on the bread. Load up lean turkey, ham, or other lean meats plus veggies. I love tomato and fresh spinach on mine. Add a steamer bag of broccoli or other veggies for a quick 15 minute meal.
So there's a few ideas that will hopefully be family friendly that you can also keep low-cal.
