Healthy freezable meals?

I'm looking for ideas for freezable meals I can make in bulk on a weekend and freeze to take to work. Ideally they must be lean and high protein.

I'm getting bored of the same old "safe options" ie chilli con carne or some form of pasta. I'm open to any ideas so surprise me. I mainly eat meat based meals however I'm also open to suggestions that are plant based.

I've not really got any limitations other than tasty (obviously), freezable, microwavable, relatively affordable and easy to prepare in bulk.

I look forward to seeing some of your recipes.
