In a medium saucepan on medium-high heat, combine salt, potatoes and enough water to cover the potatoes. Cover and bring to a boil. Reduce heat to medium-low and simmer 10-15 minutes, or until desired tenderness. While potatoes are cooking, prepare the dressing.
In a small bowl, add mayonnaise, mustard, relish and TABASCO® sauce. Stir to combine and set aside.
Drain the potatoes when they are done cooking and allow to cool before making the salad. In a serving bowl, add the potatoes, red pepper, green onions, boiled egg and dressing. Toss to combine. Garnish with red pepper, if desired.
Keep refrigerated and serve chilled.
