I'm burned out and stumped about food

Three meals a day. Three!!!! And I'm the only one coming up with them and I have absolutely no idea anymore. The worst is lunches. Our 'big' meal is dinner and I can usually come up with something for breakfast but lunch is my nemesis. I feel like we are either eating sandwiches, chicken nuggets, or mac and cheese. I'm about to smash my face on the table if I have to eat mac and cheese again anytime soon. Please help with your lunch ideas, I'll take anything.
