Mexican-style veggies

fajitas, burritos, something

1 T oil
1 onion, thinly sliced
1 sweet potato, peeled and cubed
1.5 t cumin
1/2 t chili powder
salt to taste
1 can black beans
1 red bell pepper, cut into shortish strips
2 long summer squash or zucchini, cut into thin semicircles
2 handfuls green beans, ends removed and cut in half
both halves of a lime
grated cheddar, cubed avocado, warm tortillas

Cook onion and sweet potato in oil on medium-high for a good long while, stirring occasionally and covering the pot occasionally, until onion is light brown and sweet potato is mostly done. Reduce heat to medium low, then add spices+juice of half a lime+beans, then red pepper+squash, then green beans, cooking for a few minutes between each addition. Serve on tortillas with cheese, avocado, and wedges of the other half a lime.
