LibGDX - How do you turn a mesh into a model?

I am having some trouble with my game. I have a mesh being generated with random terrain using simplex noise. The problem is that the texture I am giving the mesh is solid green, so when you are looking at the terrain you cannot see the hills very well.

So what I would like to do is render the mesh as a model so that the lighting that gets applied to my models also gets applied to the terrain. But I have looked online for quite a while now and not found anything regarding this subject.

I do not need a solution to this problem. Even just a direction to point me towards would be extremely helpful. Thank you in advance. :smiley:
