Peel the onion, dice finely and sauté in 1/2 tablespoon melted butter. Add rice and sauté briefly. Deglaze with 350 ml water, season with a little salt, bring to the boil and cover and leave to soak over a mild heat for 15 to 18 minutes.
Clean the snow peas, cut in half or thirds at an angle, sauté in 1/2 tablespoon of melted butter, add 4 tablespoons of water, season with a little salt and pepper and cover and simmer over a medium heat for 3 to 4 minutes.

It goes well with fried chicken breast with mustard sauce (the recipe can also be found here).
