Heat grill.

Peel and cut avocado into chunks; place in a medium bowl.

Mix lemon juice, basil, an 1/2 teaspoon black pepper. Drizzle over avocado chunks, toss, and set aside.

Cut chicken breasts in half crosswise.

Mix 1/2 tablespoons olive oil, salt, and remaining black pepper. Brush mixture on chicken and red bell pepper.

Grill chicken and pepper until done. Set chicken breasts aside. Cut pepper into thin strips.

While chicken and peppers are grilling, heat remaining olive oil in a large pan, add garlic and onion, and cook until tender, about 5 minutes.

Add water, bouillon, and quinoa to pan; bring to boil, cover, reduce heat, and simmer until liquid is absorbed and quinoa is cooked (about 15 to 20 minutes).
