Maybe chanterelles would be OK? I am not really fond of mushrooms, but these taste quite different. And they don't have this weird greasy texture. For me also works soy sauce - it makes mushrooms taste better. Without it, there are often just bland to me.
Hi; have you tried some millet groats, for example? You can mix it with some veggies. Also, you can for example make pancakes with ground rice. Surely you will find many gluten-free pancakes in online recipes.
