I went to the store with a budget of $30 (I also had to buy enough food for the next couple of days and gas for my car out of that $30).
Next, I heated 1 Tbsp olive oil in the largest pan I had, added the chopped veggies and a bag of frozen corn, and sautéed them until the onions were soft. Since I used a pot instead of a pan, I think it took longer than it normally would...but I had to use what I have.
Once the veggies were ready, I added a can of black beans and 1/4 Cup canned salsa and heated that through.
While the whole shibang was heating through, I warmed a couple tortillas and shredded some romaine lettuce.
UPDATE: I made breakfast using the leftover filling from the tacos. South of the border omelets! (I really should have added some hot spices to change it up a little...but, I didn't think of it...) Every time I make omelets, I whisk a special blend of garlic, basil, and some other spices and cheeses directly into the eggs. Next time I make them I'll actually measure and share so they won't be so secret ;).
Best breakfast ever! Lunch will be the topping on a bed of spinach. I'm poor...don't judge!
