Boil whole unpeeled potatoes, until tender. Stick a fork in them, if they fall off immediately they're done. Cool slightly, then gently peel skins away. Cut potatoes into cubes and place in a large mixing bowl.
Hard boil eggs, then peel. Reserve one egg for garnish. Dice remaining eggs, add to potatoes.
Microwave diced onion in 2 Tbl. water for 2 minutes. Drain, then add to the potato/egg bowl.
For the dressing...
Combine all dressing ingredients in a small mixing bowl until well blended. Then fold into the potato mixture, stirring until coated well.
To serve, line serving bowl with leafy lettuce leaves. Scoop in potato salad. Garnish with sliced hard boiled egg, scallions and a sprinkle of cajun seasoning.
Notes
For a low-carb version of this Homestyle Potato Salad, substitute steamed Cauliflower in place of the potatoes. Cauliflower 'Potato' Salad is delicious.
