What Are The Pain Points For Kids Morning Breakfast And Lunch?

Hi Expert,

I am facing little bit challenge with my 5 years old kid on morning breakfast and lunch. He likes cereal in morning, frozen foods, muffins, cakes and non-vegetarian (egg, chicken and mutton) dishes only. If I pack veg he just bring back everything whatever I packed.

What are your pain points, what are dishes you suggest for kids, can I feed frozen packed foods, and how to address this. I am getting hard time everyday with my kid on Morning breakfast and afternoon lunch.
