Notes: You can also serve this easy relish over scrambled eggs.
Pour olive oil into an 8- to 10-inch frying pan over medium-high heat. When hot, add mustard seeds and stir often just until they begin to pop, about 30 seconds. Add green onions and shrimp and stir until shrimp are warm, about 1 minute. Season with salt and pepper to taste.
