Press the extra firm tofu between paper towels to remove excess moisture, then cut into 1-inch cubes.
Slice the tempeh into similar-sized cubes to ensure even browning during the cooking process.
In a small mixing bowl, whisk together the tamari, minced fresh ginger, minced garlic, and red pepper flakes.
Heat the sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu and tempeh cubes to the hot skillet, searing for 5-7 minutes until all sides are golden and crispy.
Add the broccoli florets to the pan with a tablespoon of water, then cover with a lid to steam for 2 minutes.
Remove the lid and pour the ginger-garlic sauce over the protein and vegetables, tossing until the liquid thickens into a glaze.
Season the mixture with sea salt and black pepper, then serve immediately over the warm, fluffy quinoa.
