Sweet squash and black beans simmered with chili, oregano and tomatoes on top of crispy greens make for a satisfying and tasty main course salad with the bonus of plenty of fibre. The zesty lime yogurt dressing and cheese complement this dish perfectly. For added crunch, make some baked tortilla chips to add on top of the salad or as a side.
Preheat oven to 350°F (180°C). Line a large baking sheet with parchment paper.
In a large skillet, melt butter over medium heat. Sauté onion, garlic, chili powder, oregano, 1/8 tsp (0.5 mL) salt and 1/4 tsp (1 mL) pepper for about 2 minutes or until onion starts to soften. Add squash and sauté for 1 minute or until onion is soft. Stir in water. Cover and boil for 5 minutes.
Stir in canned tomatoes, beans and corn. Reduce heat to medium-low, cover and boil gently, stirring occasionally, for about 15 minutes or until squash is soft.
Meanwhile, cut each tortilla into 12 thin wedges. Arrange in a single layer on prepared baking sheet. Bake in preheated oven for 8 to 10 minutes or until golden and crisp. Set aside.
In a small bowl, stir lime zest and 1/2 tbsp (7 mL) lime juice into yogurt and season with a pinch each of salt and pepper.
Remove squash mixture from heat. Stir in remaining lime juice and half of the shredded cheese until melted. Season to taste with pepper and up to 1/8 tsp (0.5 mL) more salt.
In a large bowl, combine half of the lime yogurt and lettuce; toss to coat. Divide lettuce among serving plates. Spoon squash mixture on top of salad and top with remaining shredded cheese and grape tomatoes. Dollop with remaining lime yogurt, top with baked tortilla chips. Sprinkle with cilantro (if using).
