1. Stir together the tilapia, smoked salmon, Brazil nuts, kiwi, lime zest, and mayonnaise in a bowl. Keep cold. 
2. Shape rice by hand into two “pizzas,” using 250 mL (1 cup) rice each. 
3. In a small bowl, whisk together tempura flour and cold water until blended into a thick pancake-style batter. Cover rice pizzas with tempura batter and coat with Doritos crumbs.
4. Fry rice pizzas in an oil bath or deep fryer at 190°C (375°F) for about 2 to 3 minutes, until crisp and golden. Place the pizzas on paper towel. 
5. Garnish the two rice pizzas with the tilapia tartare and cut each in 4 wedges. Serve immediately.
