Fill a medium pot half full of water and bring it to a boil. Add the carrots and cook for a minute, then add the bell peppers and cook for about another two minutes. The vegetables should have softened, but retain a bit of texture (they shouldn't be mushy). Drain and set the veggies aside to cool.
Toast the sesames by putting them in a saute pan over a medium flame until they are fragrant, about 5 minutes. Pour them out of the pan onto a plate to cool.

When the carrots and peppers have cooled, stir them into the rice. Add the cucumbers. Just before serving, stir in the sesames and nori. Peel and slice the avocadoes and serve them with the salad.
