This step is the same for either recipe: Heat an 8-inch waffle iron. Coat waffle iron with cooking spray. Spread 2 cups of the tots on it; sprinkle with salt. Close and cook on medium high until nearly crisp, about 5 minutes. Open the waffle iron and fill in any holes in the waffle with more tots, then close and cook until golden and crispy, 2 to 5 minutes.
Cooking time will depend on heat of waffle iron.
Place on a baking sheet in a 200-degree oven to keep warm.
Repeat with the remaining tots.
Salmon: Top each warm waffle with crème fraîche or sour cream, 3 slices smoked salmon, spoonful caviar, a few small sprigs of dill, capers and a squeeze of lemon juice. Surround with cucumber slices, salted. Repeat for each waffle.
Prosciutto: In a small bowl, toss arugula with lemon juice. In a separate small bowl, mix together mayonnaise and mustard. Spread on top of waffle. Top with 1 ounce of cheese (tear it into 4 bits and divide equally on waffle top. Top with 3 slices of prosciutto. Return to waffle iron and press closed until cheese melts. Remove waffle from iron. Place on plate and top with 1/4 of arugula. Repeat for each waffle.

You could, of course, add radishes to either one of these 😉
