Step 1 Soak the quinoa in water overnight to soften. The next day, drain the quinoa well.
Step 2 Heat a saute pan over medium heat, and coat with a thin film of canola oil. Add the quinoa and cook, stirring frequently, until crisp, about 4 minutes. Remove from heat and transfer the quinoa to paper towels to drain and cool.
Step 3Heat a large heavy-bottom saute pan over medium-high heat until hot. Add the oil, and when it begins to shimmer, carefully add the peppers, blistering them on all sides.
Step 4Carefully stir in the fish sauce and citrus juice, tossing the peppers to coat thoroughly. Remove from heat.
Step 5Using tongs, remove the peppers (leave the oil and liquid in the pan) to a serving plate. Garnish with the crispy quinoa, shaved bottarga and salt. Serve immediately.
