Instructions
1. Prepare the Compound Butter:
- In a small bowl, combine the softened butter, thyme, parsley, garlic, lemon zest, and salt.
- Spoon onto parchment paper, roll into a log, and chill for at least 1 hour for flavors to meld.
2. Season the Filets:

- Rub with olive oil and season liberally with salt and cracked black pepper.
3. Get the Grill Ready:
- Preheat the grill to medium-high heat (450°F/230°C).

4. Grill the Filet Mignon:

5. Grill the Vegetables:
- Toss vegetables with olive oil, salt, and pepper.
- Grill corn rounds and eggplant slices for 3-4 minutes per side, until tender and lightly charred.

Tips & Tricks
- Let steaks come to room temperature for 30 minutes before grilling.
