Salut, Hélène!
First THANK YOU, THANK YOU, THANK YOU for NOT calling yourself a vegetarian! (It annoys the (@# out of me when fish/chicken eaters do that). You found the perfect way to describe your diet.

You could increase your protein without having a protein powder by adding some tempeh, tofu, seitan, quinoa, lentils to your diet.
Cheese is not really a good protein source, because it is also one of the highest sources of saturated fat (the artery clogging kind).
Your workout schedule doesn't look like you need a lot of protein: it's heavy on cardio, which is fueled by carbs (as is your brain!).
