Yellow squash

4-5 slender yellow squash with firm ends, halved and sliced
1/4 small onion, thinly sliced into rings
1/2 tsp butter
freshly grated pepper
salt to taste

Heat butter in a frying pan over medium heat. Add onions and squash, stirring to coat lightly. Cover and cook until bright yellow and just barely soft. You may need to add a little water (1-2 tsps) if it starts to stick. Stir every few minutes to cook evenly. Sprinkle with salt and pepper and serve hot.
