Basically most proteins are FODMAP friendly.
Anything sugary is not. That's why apples are high in FODMAPS. Some fruits are high in sugar than others. Be careful with vegetables that are too high in fiber.
For me, the hardest part is eating foods with NO garlic & onions. I am often on the go and need to just grab something from the nearest deli. Almost everything that is processed will contain garlic or onions or BOTH.

Even ketchup and some mayos contain one or the other. There is only one or two obscure cultures whose cuisines do not use garlic or onions, and one is due to religious reasons.
Basically, if I am out, I will go to McDonalds and get a plain hamburger with no salt, (as I am also watching my sodium intake.) I cannot even have a cheeseburger as the American cheese has FODMAPS (and lactose.) I can do the tiniest smidge of ketchup on it. I usually discard the bun, especially one topped with sesame seeds.
I'll have a salad with FODMAP friendly veg and just drizzle it with olive oil. Sometimes vinegar or lemon juice. NO salad dressings as they usually contain garlic &/or onions.
When cooking at home, as a PP said, I broil my meats with just olive oil, light salt & pepper. If you get a good cut of meat, it will be flavorful enough that it doesn't need a lot of spices.
There are lists of FODMAP friendly and high FODMAP foods put out by Monash University. They even have an app. I just Google the "specific food Monash Fodmap" and see if I can eat it.
