Crush or finely chop the garlic. Finely chop the onion. Drain and rinse the corn and beans, keeping them separate.
Step 2 — Start chilli
Heat 2 tsp olive oil in a medium deep frypan over high heat. Cook the corn, garlic and half the onion, stirring regularly, for 2 mins or until the onion is slightly softened.
Step 3 — Add seasoning
Add the Tex-Mex seasoning to the corn mixture and cook, stirring, for 30 secs or until fragrant.
Step 4 — Simmer chilli
Add the beans, diced tomatoes, 60ml (¼ cup) water and ½ tsp sugar to the corn mixture and bring to a simmer. Reduce the heat to medium and cook, stirring occasionally, for 8 mins or until slightly reduced. Taste, then season with salt and pepper.
Step 5 — Prep salsa and yoghurt
Meanwhile, cut the lime into wedges. Finely chop the tomato. Coarsely chop the coriander leaves and finely chop the stems. Combine the yoghurt and a pinch of salt in a bowl, then add the chipotle and swirl through. (We've suggested this amount of chipotle for flavour, but if you prefer less heat, reduce the chipotle to taste.)
Step 6 — Make salsa and serve
Combine the tomato, coriander, remaining onion, ½ tsp red wine vinegar and a pinch of sugar in a bowl and season with salt and pepper. Divide the corn chips, bean chilli and salsa among bowls. Serve with the chipotle yoghurt and lime wedges.
