Preheat the oven to 400°F (200°C). Line a sheet pan with parchment paper or a silicone baking mat.
In a large bowl, stir together 2 tsp Gochujang, 2 tbsp sesame oil, and 2 tbsp soy sauce.
Add 2 cups brown rice (cooked and cooled) to the gochujang mixture and toss until the rice is evenly coated and any clumps are broken up.
Spread the coated rice in an even layer on the prepared sheet pan. Place in the oven and bake 15–20 minutes, stirring and spreading the rice every 5 minutes with a spoon or spatula so it crisps evenly and any wet spots dry.
While the rice bakes, prepare the vegetables and herbs: steam 1 cup peas until tender and cool them slightly; chop 1 Persian cucumber, finely slice 3 green onions, chop 1 avocado (dice and reserve), and chop 1/4 cup mint and 1/4 cup cilantro.
Make the dressing: whisk together 1 tbsp honey, 2 tbsp soy sauce, 1/4 cup Tahini, 1/4 cup lime juice, and 1/4 cup water until smooth and combined (it may start lumpy—keep whisking).
When the rice is crisp and lightly browned, remove it from the oven and let it cool for a few minutes.
In a large bowl, combine the crisped gochujang rice with the steamed peas, chopped cucumber, sliced green onions, chopped mint, and chopped cilantro. Gently fold in the diced avocado.
Drizzle the dressing over the salad and toss gently until everything is evenly coated. Serve immediately.
