### Step-by-Step Instructions

#### 🍳 Caramelizing the Onions

1. **Chop the Onions:** Start by finely chopping the red onions.

2. **Heat the Pan:** Place a pan on medium heat and add a generous amount of butter.

3. **Add Ingredients:** Once the butter melts, add the chopped onions along with a pinch of salt.

4. **Cook:** Cover the pan with a lid and let the onions soften for about half an hour. Stir occasionally.

5. **Add Sweetness:** After they’ve softened, mix in a bit of brown sugar and a splash of balsamic vinegar. Continue cooking until the onions are sticky and jam-like, then let them cool down.

#### 🥩 Cooking the Steak

1. **Prepare the Steak:** Take the sirloin steak out of the fridge at least 30–40 minutes prior to cooking to reach room temperature.

2. **Season:** Drizzle olive oil on the steak and rub in salt and finely ground black pepper for seasoning.

3. **Heat the Pan:** Heat a pan until it’s extremely hot.

4. **Render the Fat:** Place the steak in the pan and let it cook for a few minutes to allow some fat to render out.

5. **Add Garlic:** Toss in a clove of garlic for flavor.

6. **Sear the Steak:** Cook the steak to achieve a nice sear on either side. Butter can be added for extra flavor, along with herbs like rosemary and thyme.

7. **Rest the Steak:** After cooking, let the steak rest briefly before slicing.

#### 🥗 Preparing the Mustardy Mayo

1. **Mix Ingredients:** Combine three parts Japanese mayonnaise to one part Dijon mustard and a splash of whole grain mustard in a bowl.

2. **Season:** Add some freshly ground black pepper for an extra kick.

#### 🥪 Assembling the Sandwich

1. **Slice the Bread:** Cut the crusty bread to create the sandwich base.

2. **Spread the Mayo:** Generously spread the mustardy mayo on the bottom piece of bread.

3. **Add Onions:** Layer the caramelized onions on top of the mayo.

4. **Slice the Steak:** Thinly slice the rested steak and place it over the onions.

5. **Add Cheese:** Crumble some blue cheese over the steak.

6. **Top with Rocket:** Add fresh rocket for a hint of freshness and crunch.

7. **Final Touch:** Place the other half of the bread on top and press down slightly.
