Pasta: Cook 8 oz uncooked ditalini pasta to al dente according to package instructions. Drain then transfer back to the pot. Toss with 1 tsp olive oil to prevent sticking, then let it cool while you prepare everything else.
Sauce: Stir together all Sauce ingredients.
Assemble: Either toss everything together in a large bowl, or meal prep it in jars. To meal prep, spoon Sauce evenly into 4 large (32-oz) mason jars. Evenly divide ingredients into the jars in this order: beans, corn, pasta, green onions, cilantro, and cheese (sprinkle with optional tajin). Close lids and store in the fridge for up to 5 days. To serve, dump the contents of a jar into a bowl and stir!
