Here's something I tried recently:
Take one can of cream of mushroom soup and one stick of saltine crackers. Mix together then scoop out and form balls and deep fry them. It sounds nasty but its weird how close they taste to morels. It's not exactly like morels but its close enough you could fool some people.
When cooked properly they will be nice and browned but the inside will still be a little soft and mushy. You'll have to kinda play with it to get the right consistency (the good news is the ingredients don't cost a lot).
4 cans of soup and 4 sticks of crackers (1 box) will make roughly 75 golf ball sized fauxshrooms (for lack of a better word).
The best part of this is you can eat as many as you like and not get the shits like you can from wild mushrooms.
If you're trying to avoid getting hot though standing over a deep fryer might be a bad idea.
