Preheat oven to 425F. Line a large pan with parchment paper.
Toss all crispy rice ingredients together on the pan, spread out evenly on ½ of the pan.
Toss all the zucchini ingredients together on the empty half of the pan, then spread out evenly.
Roast the rice and zucchini for 15-20 minutes, flip the rice and zucchini, then roast another 15-20 minutes, until rice is crispy. Let rest 5 minutes on the pan.
To make the salad dressing, combine all ingredients in a small bowl and whisk until smooth. Set aside.
In a large bowl, add the canned tuna. Break up with a fork to finer pieces. Add the chopped fennel, tarragon, mint, artichokes and sliced red onion. Toss to combine, then add the salad dressing to preferred amount.
Lastly, toss in the crispy rice and zucchini to enjoy warm!
