Choosing the Right Cut of Steak

Sirloin is ideal for meal prep because it is:

• Lean yet tender

• High in protein

• Affordable compared to premium cuts

• Quick to cook

You can also use flank steak or top round if preferred. Trim excess visible fat for a leaner result.

Step 1: Prepare the Marinade

In a bowl, whisk together:

• 3 tablespoons (45 ml) balsamic vinegar

• 1 tablespoon (15 ml) soy sauce

• 1 teaspoon (5 ml) Dijon mustard

• Minced garlic

• Salt, pepper, and rosemary

Add steak cubes and toss to coat. Let marinate for 15–30 minutes for deeper flavor.

If short on time, even 10 minutes makes a difference.

---

Step 2: Sear the Steak Bites

Heat 1 tablespoon (15 ml) olive oil in a large skillet over medium-high heat.

Add steak cubes in a single layer. Avoid overcrowding the pan.

Sear for 2–3 minutes per side until browned and internal temperature reaches 135°F (57°C) for medium-rare or 145°F (63°C) for medium.

Cook in batches if necessary.

The key is high heat for a flavorful crust without overcooking.

---

Step 3: Create the Garlic Balsamic Glaze

Once steak is nearly cooked:

1. Reduce heat to medium.

2. Pour remaining marinade into the skillet.

3. Let simmer 2–3 minutes until slightly thickened.

Toss steak bites to coat evenly in the glaze.

Remove from heat immediately to prevent overcooking.

Step 4: Prepare Meal Prep Sides

Brown Rice

Cook 2 cups (400 g cooked) brown rice according to package instructions.

Roasted Broccoli

1. Preheat oven to 400°F (200°C).

2. Toss 4 cups (600 g) broccoli with 1 tablespoon (15 ml) olive oil and 1/2 teaspoon (2.5 g) salt.

3. Roast for 18–20 minutes until tender with crispy edges.

Roasted vegetables add fiber and micronutrients to balance the protein.

Step 5: Assemble Meal Prep Containers

Divide evenly into 4 containers:
