Thoroughly rinse any fresh produce and pat dry. Combine bolognese sauce, poblanos, and half the seasoning blend (reserve remaining for enchiladas) in provided tray. Stir in 1/3 cup water. Cover with a damp paper towel and microwave until poblanos start to soften, 3-4 minutes. While sauce heats, drain black beans. Place tortillas on a clean work surface and top with an even layer of black beans, corn, remaining seasoning blend, a pinch of salt, and cheese. Roll tortillas tightly, and place in provided tray, on sauce, seam-side down. Use short side of tray to fit more enchiladas; they should fit snugly. Cover again with a damp paper towel. Microwave on high until warmed through, 3-4 minutes. Remove tray from microwave. To serve, place enchiladas on sauce and top with sour cream. Bon appétit!
