Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine the cooked quinoa or rice, shredded cheese, chopped vegetables, eggs, garlic powder, and seasoning. Mix everything well until fully combined.
Grease a mini muffin tin with cooking spray or oil to prevent sticking.
Scoop the mixture into the mini muffin cups, filling each one about three-quarters full.
Bake in the preheated oven for about 15-20 minutes, or until the bites are golden brown on top.
Remove from the oven and let cool for a few minutes before carefully removing them from the tin.
Enjoy warm or let cool and pack for later!
