unhealthy foods
Instead of focusing on healthy versus unhealthy, focus on what your body needs and make adjustments where you're able based on that. If she makes food that includes a protein but doesn't include vegetables, focus on where you can find fiber to make up the difference.
You can eat plenty of "unhealthy" food as long as you're also getting your nutrition needs met. Look for fiber and protein where you can, be somewhat mindful of calories and sugar intake, and use carbs for energy.
