8oz. pasta (elbow or shell) $0.75
1 Tbsp olive oil $0.16
1 small yellow onion $0.52
2 cloves garlic $0.16
1 cup frozen corn kernels $0.50

1 cup shredded sharp cheddar $0.83

INSTRUCTIONS
Cook the pasta according to the package directions (boil 7-10 minutes, or until al dente), then drain in a colander.
While waiting for the pasta water to boil and the pasta to cook, dice the onion and mince the garlic. Sauté both in a large pot with the olive oil over medium heat until they are soft and transparent (about 5 minutes). Drain the diced tomatoes, then add them to the pot with the frozen corn and chili powder. Continue to sauté until the corn has heated through (about 3 minutes).
Turn the heat off and add the drained pasta and Greek yogurt. Stir until the pasta is coated in the creamy sauce. Add the cheese and stir until the residual heat has melted it into the sauce. If you pasta has cooled too much to melt the cheese, keep the burner on low as you stir the cheese into the sauce. Serve hot sprinkled with the sliced green onion
