If using, cook cauliflower rice according to instruction, or regular rice. Keep warm.
In skillet, heat a bit of olive oil and garlic. Add sliced mushrooms and sauté until tender. Remove and set to the side (start a side plate, as we will be preparing in steps).
In now empty skillet, warm sesame oil and add matchstick cut zucchini, carrots and green onions, and season with salt. Sauté until tender and browned. Remove and add to side plate.
Add a dash of olive oil to the skillet to pick up any seasoning and add shrimp. Cook through, developing a crisp exterior. Add to side plate.
Add a dash of sesame oil and chopped ginger. Sauté and add mustard greens. Cook until greens are wilted. Salt as desired.
While pan is still hot, crack eggs and turn heat lower, adding a splash of water. Allow to cook until sunny side up.
While egg is finishing, assemble bowl. First, layer cauliflower rice, then place mushrooms, sautéed vegetables, pickled cucumbers, shrimp, and mustard greens. Top with a fried egg and drizzle with gochugaru sauce. Sprinkle with sesame or chia seeds and serve. Enjoy!
