Grits and beans, maybe with greens and fried eggs -- a base recipe that is in regular rotation.

Oat milk works just fine.

Ingredients Step
2 c. broth
2 c. milk
Bring to a boil.
⅛ onion, ideally red onion
citrus or apple cider/sherry vinegar
salt
Thinly slice onion, then let sit in acid with a bit of salt to make a quick pickle. (Alternatively, crack open a small can of pickled Mexican veg.)
1 c. grits or polenta Stream in to the 4 cups of boiling liquid while whisking. Cook over low, stirring frequently, until completely tender, likely 20-40 minutes. Don't rush this.
¾ c. broth
3 c. black beans (2 cans)
Mexican oregano
cumin
smoked paprika
sweet paprika
garlic powder
onion powder
chili powder
Cook over low heat, stirring occasionally, until warm. Adjust seasonings until tasty.
garlic
butter
chopped greens (kale, collards)
salt
pepper
Saute garlic in butter, then add greens, salt, and pepper. Stir over high until greens begin to wilt (1-2 minutes), then reduce heat to 3-5 minutes until tender and water has evaporated.
eggs Fry.
½ c. cheese (cheddar, parmesan, Manchego, nutritional yeast, etc.)
2 T. butter
Vigorously stir into grits, until creamy and vaguely fluffy.
avocado
quick pickled onion
scallions
cilantro
salsa
hot sauce
lime
Add atop bowls of grits, beans, and greens.
