Dinner in the desert

give me your ideas! I've run out of new ideas when it comes to making dinner in Loki and the grocery selection is slim, since everything has to come on a truck from Kitale- a 12 hour drive on  washboard dirt roads...only the heartiest of produce can make it, no dairy except for a few shops that have yogurt or buttermilk every blue moon or so. What should I make? This is what I can buy around here:

beef
rice
spaghetti noodles
macaroni noodles
lentils
red beans
canned kidney beans
canned chick peas
canned mushrooms (expensive)
tomato paste
chicken or beef bouillon cubes
white flour
corn meal
coconut milk
peanut butter
olive oil
canned green beans
canned corn
canned fruit (very expensive)
oatmeal
tuna
cabbage
onions
potatoes
butternut squash
carrots
green pepper (sometimes)
oranges
lemons
kale
tomatoes
avocados (sometimes)
mangoes (sometimes)
pineapple
passion fruit (seasonally)
margarine
powdered milk
