If you're saying you don't have a grill, you have several options.
You can broil the chicken under your oven broiler. Use a foil covered cookie sheet if you don't have a broiler pan.
You can bake the chicken breasts in the oven at 350 F. Again, use the same cookie sheet.
You can also cook them on the stovetop.
If I misunderstood your question, please provide some more info.
