Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with one teaspoon of olive oil, salt, and pepper, then spread them in a single layer on the baking sheet.
Roast the broccoli for 15-20 minutes until the edges are tender and slightly charred.
While the broccoli roasts, prepare the quinoa according to package instructions or warm up pre-cooked quinoa.
In a small pan, lightly sauté the minced garlic with a tiny drop of oil until fragrant, then fold it into the warm quinoa.
Slice the beef into thin, even strips and season them with a pinch of sea salt and cracked black pepper.
Heat the remaining teaspoon of olive oil in a heavy skillet or cast-iron pan over high heat.
Add the beef strips to the hot skillet and sear for 2-3 minutes, tossing occasionally until browned on the outside but still tender.
Arrange the garlic quinoa in a bowl, top with the seared beef strips, and serve the roasted broccoli on the side with an optional squeeze of fresh lemon.
