1. Rinse the rice, then cook it in boiling salted water (or in the Monsieur Cuisine) for the indicated time (usually 20-25 minutes for brown rice).
2. Cut the chicken cutlets into strips. Slice the onion and garlic.
3. In a sauté pan or the bowl of your food processor (if "sauté" mode is available), heat the olive oil.
4. Sauté the onion for 2-3 minutes, then add the chicken and garlic. Season with salt, pepper, and paprika.
5. Let it brown for 5-6 minutes.
6. Stir in the sliced mushrooms, light cream, and mustard. Cover and simmer for about 10-15 minutes (until the rice finishes cooking). Adjust the seasoning.
7. Serve the creamy chicken over the brown rice.
