Trim radish, halve, and slice into thin half-moons. Peel and halve onion. Cut halves into 1/2” dice. Stem poblano pepper, seed, and cut into 1/2" dice. Cut a few thin rounds from pointed end of jalapeño pepper for garnish. Stem, seed, and mince remaining jalapeño. Discard seeds if you prefer less spice.

Heat 1/2 tsp. olive oil in a medium pan over medium-high heat. Add ground beef to hot pan and cook 4-5 minutes, or until almost no pink remains. Add onion, poblano pepper (to taste), and 2 tsp. minced jalapeño (to taste) to hot pan and cook 2 minutes. Add frozen corn and seasoning blend. Use to taste if you prefer less heat. Cook 5 minutes and remove from heat. Season with 1/4 tsp. salt and allow to cool 3-5 minutes. Stir in 1/4 the Oaxacan cheese.

Pour 1/4 cup enchilada sauce in casserole dish (use a dish large enough to fit six rolled tortillas), coating the bottom. Place one tortilla on a clean cutting board. Add 1/3 cup filling to tortilla, tightly roll up, and place in casserole dish seam-side down. Repeat for remaining five tortillas. There will be filling left over, which can be placed in casserole dish around enchiladas or served on the side. Don't be tempted to overfill tortillas. Make sure ends overlap and have a chance to seal while baking.

Pour remaining enchilada sauce over enchiladas and top with remaining Oaxacan cheese. Spray a piece of foil with cooking spray and place over casserole dish, sprayed side down. Tightly seal foil and bake 15 minutes. Remove foil and bake an additional 7 minutes, or until cheese is bubbly.

Place three enchiladas on a plate. Ladle any remaining sauce from casserole dish on plate with enchiladas. Garnish with radishes, sour cream, and jalapeño rounds (to taste).
