Brain-Healthy Greek Grilled Steak Salad

Fresh vegetables, healthy fats, and grilled steak come together in one easy meal that fits both Mediterranean and ketogenic eating.

Here is the brain-health connection: what we eat can influence several modifiable risk factors for dementia, including cardiovascular health, blood pressure, blood sugar, and inflammation.

A Mediterranean-style diet puts vegetables, healthy fats, and minimally processed foods at the center of the plate. Greater adherence to this pattern has been associated with a lower risk of dementia.

Prefer a mildly ketogenic approach? KetoFLEX 12/3, used in the Bredesen Protocol’s PreCODE and ReCODE programs, combines plant-rich, low-glycemic foods with healthy fats, mild ketosis, and time-restricted eating. A 2026 peer-reviewed perspective paper by Rammohan Rao, PhD, Dale Bredesen, MD, and colleagues explains how this approach may support insulin sensitivity, brain energy metabolism, and other pathways related to cognitive health.

Good news: this salad plays nicely with both approaches. Fill most of the plate with vegetables, then adjust the steak, avocado, and olive oil to match your personal macronutrient goals. For fewer carbohydrates, make the simple vinegar swap in the dressing. No nutritional gymnastics required.

Greek Grilled Steak Salad

Prep time: 10 minutes, plus marinating
Cook time: 15 to 20 minutes
Serves: 4 to 6

Dressing and Marinade

1/4 cup balsamic vinegar
For the lower-carbohydrate version, use red wine vinegar.

1/2 cup extra-virgin olive oil

Juice of 1 lemon

1 teaspoon Dijon mustard

1 teaspoon Italian seasoning

Sea salt and freshly ground black pepper to taste

Salad

1 to 2 pounds organic grass-fed, grass-finished flank steak

Extra-virgin olive oil for grilling

1 avocado, sliced

Juice of 1/2 lemon

Mixed organic salad greens

1 organic cucumber, chopped

Cherry or grape organic tomatoes, halved

Red onion, thinly sliced

Kalamata olives

Crumbled sheep milk feta cheese

Directions

1. Make the marinade

Whisk together the vinegar, olive oil, lemon juice, Dijon mustard, Italian seasoning, salt, and pepper.

Place the steak in a shallow dish or sealed container. Pour approximately half of the mixture over the steak, reserving the remainder for the salad.

Marinate the steak in the refrigerator for up to two hours or overnight. Do not reuse marinade that has been in contact with raw meat.

2. Prepare the salad

Place the greens, cucumber, tomatoes, red onion, and olives on a large platter.

Toss the avocado slices gently with lemon juice to help prevent browning. Add them to the salad, and top with crumbled feta cheese.

Already gorgeous, and we have not even invited the steak yet.

3. Grill or broil the steak

Grill or broil until the steak reaches your desired doneness. For food safety, cook the steak to an internal temperature of 145°F, followed by a minimum three-minute rest.

Transfer the steak to a cutting board and allow it to rest 10 minutes before slicing thinly across the grain.

4. Bring it together

Arrange the sliced steak over the salad. Drizzle with the reserved dressing and serve.

One Simple Action

Put this salad on next week’s menu. Pick the version that fits your plan, pile on the vegetables, and call dinner handled.
