What kind of sentences do you need? You could say, for example, "Cada día como manazanas para el desayuno", or "Every day I eat apples for breakfast". It really depends on what your teacher specifically asked for in terms of verb forms and sentence complexity.
You can also say, "Quisiera comer un desayuno antes de ir me a la escuela," or, "Que tenemos para comer esta tarde mama?" or, "Tengo tanta hambre, espero que la comida en la escuela me satifase." Those are just some examples. If you want more you can ask me :)
