In a bowl, combine olive oil, lemon juice, minced garlic, chopped herbs, salt, and pepper. Add chicken, sausages, and salmon, ensuring they are well-coated. Marinate for at least 30 minutes.

Prepare Vegetables

Chop bell peppers, zucchini, and red onion into bite-sized pieces. Husk corn and cut it into halves if desired. Toss vegetables in olive oil, salt, and pepper.

Cook Quinoa

In a saucepan, bring vegetable broth to a boil. Add quinoa, reduce heat, cover, and simmer for 15 minutes or until liquid is absorbed. Fluff with a fork and stir in feta cheese and olives.

Grilling

Preheat Grill

Preheat your grill to medium-high heat.

Grill Proteins

Place marinated chicken and sausages on the grill. Cook chicken for 6-7 minutes per side, and sausages for about 10-12 minutes, turning occasionally. Grill salmon for about 4-5 minutes per side.

Grill Vegetables

Use a grill basket for the vegetables. Grill for about 10-15 minutes, tossing occasionally until they are tender and slightly charred.
