Hi guys!

I usually make the same lunch for work and I prepare enough to last for the week.  I'm not bored of it, but I also want to try some more ideas.

I'm currently having white rice with ground beef prepared akin to what you would call chili, and apples.  I also have only two pots (since I'm renting just a room I don't want to purchase more stuff)

Got any ideas for other easy to prep lunches that don't need me to have a full set of pans and pots?

Depends on what kind of foods you like to eat the most and what is readily available at a reasonable cost where you live.  Think starch + a sauce with protein and vegetables, which is perfect for two pots:

Rice + beans
Pasta + stewed chicken with vegetables
Cous cous + vegetable stew
Rice + curried chickpeas and vegetables.

Then add a piece of fruit and perhaps some bread.  Since you are in Mexico, you have access to good, healthy fresh breads, tortillas, etc.

Meal prep is popular now, just search for hot lunches:
