Teriyaki sauce, minced garlic, touch of honey, sliced hot peppers (for you). Marinate for 1 hour then grill. Be it steaks or filets.
For whole salmon, squeeze two lemons inside, season with salt and pepper, stuff with fresh herbs such as basil, parsley, thyme, and dill. Oil both sides with olive oil, then grill until just done. You can melt some butter, squeeze in some lemon juice, some minced fresh parsley, and serve it alongside.
For whole sides, you can cook in a foil pouch. Layer sliced red onions and lemon slices on a large double layer of foil. Lay the salmon on top, skin side down. Squeeze on some lemon juice, salt and pepper, and few minced herbs, maybe some diced tomatoes, or a splash of white wine or vermouth. Bring up the foil and seal tighly. Cook for 15-20 minutes. Be careful when opening, there will be a lot of steam built up insdie.
