Step 1

Heat vegetable oil and butter in a large skillet over medium heat. Add onions and sauté for 5 minutes, or until onions are translucent. Add garlic and cook for 1-2 minutes, or until fragrant.

Step 2

Add bacon, if using, and cook until crisp. Drain fat, then add broccoli, brussel sprouts and cabbage to the onion mixture. Season with salt and pepper.

Step 3

Brown vegetables for 5 minutes, stirring frequently.

Step 4

Add mashed potatoes to the skillet, pressing down to flatten to form a patty. Brown about 6-7 minutes.

Step 5

Carefully flip the potato and vegetable patty. Cook an additional 6-7 minutes, or until well-browned with a crispy crust. (If needed, invert potato onto a plate and slide back into skillet.)

Step 6

Transfer onto a platter. Cut into wedges for serving.
