I really love ostrich meat myself.
But to be honest, most of these meats taste like other meats. Venison, ostrich and buffalo are all comparable to beef, for instance. I also like pheasant, but that is comparable to chicken. They are not exactly the same but pretty close.
I think what you need is new WAYS to cook the beef, and also some breaks from meat. How about something yummy using things like barley, lentils, quinoa, beans, nuts, couscous, pasta etc - those are filling things, and lentils, quinoa and beans have lots of protein!
Go to some cooking websites and look up new and interesting ways to prepare meat, or some vegetarian websites. They often have fantastic ways to make veggies and grains that are tasty, unique and healthy.
I’m Italian so one of my ‘staples’ is to saute some vegetables with olive oil, garlic and onion and toss them with pasta. You can get creative with that (eggplant is one of my faves) and it’s easy to make.
A recipe I made up on the fly that I really enjoyed was stuffed bell peppers with couscous, golden raisins and some other veggies.
One of my favorite meat recipes is Pizziola (Italian meat loaf) which is mixing ground beef (or ostrich, venison, etc) with oregano, parmasan cheese, onion and an egg, putting it in a square pan, and topping it with onion slices, fresh tomato slices and more parmesan cheese and baking it until it is done.
Ask you friends, or go to cooking sites for ideas Maybe try something from an ethnicity you usually don’t cook with that has interesting spices or flavor combinations. Things like curry, cinnamon, cardamom, sumac…found in Indian and Middle Eastern foods can make a really interesting dish. I also love thai food (lots of spicy chili, lemongrass, curry, etc).
Sorry, I love food and cooking, as if you couldn’t see
