Yes and no.
You have to remember that a large percentage of visibly minorities come from very social conservative (or even just straight horrific) counties, and there's a heavy passing those values to their children. Religion often plays a roll too.
They may also be anti immigration due to racism against other minorities, even at the peril of their own group.
The most overt racisism I've ever encountered personally was the treatment of Koreans in Japan for example. I know some of the other groups absolutely despise each other too.
It's a complicated situation unfortunately.
Your biggest issue is going to be the protein source, most of them require refrigeration.
Try things with canned meats, like canned tuna with Mac and cheese.
You can get canned chicken to go with some sort of pasta and tomato sauce.
Canned beef with potatoes.
Just be careful of making too much so there's no leftovers
