Peel and grate or mince ginger; transfer to a small saucepan.
Using a strainer or colander, rinse the rice under cold, running water, then drain and transfer to the saucepan with the ginger. Add water and salt; bring the mixture to a boil over high heat.
1 cup jasmine rice
2 cup water
¼ tsp salt
Once the liquid comes to a boil, stir the mixture, cover the saucepan, and reduce the heat to low. Cook the rice until the liquid is fully absorbed, 15-18 minutes. Once done, remove the rice from the heat and let it stand, still covered, for 5 minutes.
Meanwhile, peel and mince garlic; transfer to a medium bowl along with mayo and whisk to combine.
2 cloves garlic
½ cup mayonnaise
Trim and thinly slice green onions; add to the bowl with the mayo.
Trim, seed, and small dice bell pepper; add to the bowl.
Chop or tear salmon into small pieces and add to the bowl. Stir to combine the salmon mixture and set aside.
2 (4 oz) pkgs smoked salmon
Place sesame seeds, oil, vinegar, soy sauce, sugar, chili powder, and salt in a large bowl. Whisk to combine the dressing.
1 tbsp sesame seeds
2 tsp toasted sesame oil
2 tsp rice vinegar
2 tsp soy sauce
1 tsp brown sugar
½ tsp chili powder
⅛ tsp salt
Trim and medium dice cucumber; add to the bowl with the dressing.
Cut the snap peas crosswise into ¼-inch pieces; add to the bowl.
Uncover the rice and fluff with a fork. Add vinegar and sugar; stir to combine, then spread the rice out on a baking sheet pan to cool, about 5 minutes.
1 tsp rice vinegar
½ tsp brown sugar
Meanwhile, halve and pit the avocados; scoop out flesh with a spoon and medium dice. Add to the bowl with the other veggies and gently stir to combine the salad.
Place a ⅓-cup of the salmon mixture in a small cup or bowl; top with a ½-cup of rice and press gently to secure. Once the stack is complete, flip the cup or bowl onto a plate; tap on the bottom to loosen the stack. If the rice is sticking, run a knife around the edge before flipping.
Repeat with remaining salmon mixture and rice, creating 2 stacks per plate.
