Place a sheet of nori on your work surface or bamboo mat, rough side facing up. 2. Lightly wet your fingertips in cool water.
Spread ¾ cup / 150 g (5.3 oz) of sushi rice evenly over the entire surface of the nori. 3.
Sprinkle ¼ of the crushed tortilla chips over the rice and press gently to adhere. 4. Carefully flip the nori sheet over so the rice side is facing down. 5.
Arrange your fillings in a horizontal line across the center of the nori.
Layer 2 avocado wedges, ¼ of the poblano strips, ¼ of the red bell pepper matchsticks, and 1 tablespoon (15 ml / 0.5 fl oz) of the smashed black beans. 6.
Using your thumbs to lift the edge of the nori closest to you, begin to roll it over the fillings, tucking tightly to create a compact cylinder. 7.
Continue rolling until the roll is sealed. If you have a bamboo mat, use it to gently press and shape the roll into a firm, even log. 8.
Place the finished roll seam-side down.
Repeat with the remaining to create three more rolls. 9.
Dip the tip of a very sharp knife in water.
Slice each roll into 8 equal pieces, wiping the blade clean between cuts.
Serve immediately with Ponzu Sauce or salsa, if desired.
