Preheat oven to 400 degrees. Spray a sheet pan with non-stick oil and set aside.
Cut bok choy into quarters, lengthwise, leaving the ends in tact so that the stems don't separate. Rinse in cold water, making sure to get between the stems. Thoroughly pat dry then place on prepared sheet pan, leaving at least one-inch between each piece.
Peel and grate ginger into a bowl. Mince or grate garlic and add to bowl. Squeeze in the juice of one lemon.
Add soy sauce, sesame oil, avocado oil, honey, crushed red pepper, sea salt, and black pepper to bowl. Mix vigorously to combine.
Drizzle sauce over top of each piece of bok choy, making sure to get sauce on the dark green leaves. Reserve about two spoonfuls of sauce for serving.
Transfer pan to oven and roast for about 10 minutes. Bok choy will be fork tender and very slightly browned. Leaves will be dried and crisp.
If using whole almonds, chop them into small pieces while bok choy roasts. Garnish finished dish with almonds, sesame seeds, and more sauce, if desired.
