[Help]Have some ingredients, not sure what to do with them.

Hi, so today I realised I need to up my game and perhaps surprise my gf. I bought the following:

-red potatoes

-yellow potatoes

-black eyed beans (desiccated?)

-red adzuki beans (desiccated?)

-black lentils (desiccated?)

-barley (desiccated?)

-red onion

-chicken breast

-mushrooms (sort of like this, brown top, not sure what they're called)

-Quinoa

-Bulgur wheat

-Couscous

What can I prepare with the above ingredients, if anything? Anything which can perhaps be prepared the day before and reheated at work? Desiccated means they were sold uh .. in some kind of burlap sack where you'd scoop them out yourself, and they're the consistency of peanuts at the moment. Got some spices at hand too.

Important note: I'm allergic to cheese.

Thanks in advance for any ideas you might give!
