Make a garlic aioli by combining the mayonnaise, yogurt, cream, parsley and garlic in a small mixing bowl. Season with salt and pepper.
Slice the potatoes as thinly as possible. (Use a mandoline for even thickness.) Heat at least 2 inches canola oil to 350 degrees F in a deep fryer or a large pan. Fry the chips until golden brown. Drain on paper towels and season with salt.
Grill or pan-fry the sausage until browned on both sides, then slice.
Score the foie gras and sprinkle with salt. Heat a skillet until very hot (just smoking). Add the foie gras, scored-side down, and cook for about 20 seconds. Flip and cook for another 20 seconds. Remove from the skillet.
Toss the potato chips, sausage, cilantro, giardiniera, curry powder and a healthy dollop of the garlic aioli in a mixing bowl, being careful not to break the chips too much.
Arrange the chips and sausage on serving plates and top with the hot foie gras.
