Some are silly (like grilled cheese) but others aren't so bad. I've been asked before about how to roast a chicken, how to saute greens, how to oven roast veggies. (Do it ala Tamar Adler. Roast all your veg in advance, place in Mason jars in the fridge and then you have them ready to eat all week long in various incarnations with zero excuses. Sandwich wraps, soups, slightly warmed as a side or tossed with rice or quinoa-perfection!)
They mention baking fish in foil. I make mine ala papillote, meaning paper. Super easy: cut parchment paper into squares. Using whatever veggies on hand depends on the order of veg. If you have stalky or fiberous veg make a small, thin layer on the bottom, then add fish (salmon is beautiful here but if you have a fresh steak of something you've caught, go for it), then add the more liquidy veg (tomatoes, mushrooms, spinach, etc). Drizzle with olive oil and season to taste. (Sea salt and coarse black pepper is always good. Sometimes I use herbes de provence but a friend uses Italian. I've also used a cajun seasoning in the past.) Wrap the paper like a present. You can either tie it off with string or wet the corners with water and firmly press down on the paper. The paper will steam the fish and veg beautifully while baking. Bake at 350 for about 10-15 minutes for most fish. White wine, lemon, champagne vinegar, etc also taste fantastic when dressed before steaming.
