Ingredient Notes & Substitutions
CORN
Use 2–3 ears of fresh corn, husked and cleaned. Look for bright yellow kernels and firm cobs with moist silk. Grilling brings out natural sweetness. Frozen corn can be a backup, but fresh is best for that charred flavor.
ZUCCHINI
About 2 medium zucchinis, sliced lengthwise. Choose firm, glossy zucchinis without soft spots. If you prefer, yellow squash can be substituted. Grilling gives them a slightly smoky, tender bite.
AVOCADO
One ripe avocado adds creaminess and richness. Look for slight softness when gently pressed but avoid mushy spots. Substitute with hummus or soft cheese if needed.
GREENS (ARUGULA OR SPINACH)
A handful or two of fresh greens provides a peppery or mild base. Baby spinach is tender, while arugula adds a spicy note. Wash and dry thoroughly to keep the salad crisp.
GREEN ONIONS
2–3 stalks sliced thinly add a subtle sharpness. Scallions work well too.
DRESSING
A simple vinaigrette with olive oil, lemon juice, and a touch of salt and pepper complements the flavors. You can also add a splash of balsamic for sweetness or a pinch of chili flakes for heat.
Step-by-Step Instructions
- Prepare the grill or grill pan.
Heat over medium-high. Brush corn and zucchini lightly with olive oil. - Grill the corn.
Turn occasionally until kernels are lightly charred and fragrant, about 8–10 minutes. Remove from heat and let cool slightly, then cut kernels off the cob. - Grill the zucchini.
Place zucchini slices on the grill until tender with grill marks, about 3–4 minutes per side. Cut into bite-sized pieces after grilling. - Prep the greens and avocado.
Wash and dry your arugula or spinach. Slice the avocado just before serving to prevent browning. - Assemble the salad.
In a large bowl, combine greens, grilled corn, zucchini, avocado, and sliced green onions. - Dress and toss.
Drizzle with your vinaigrette and toss gently to coat all ingredients. Serve immediately for a fresh, crisp texture.

Expert Tips
- Grill zucchini and corn just until tender to preserve texture and natural sweetness.
- Slice avocado last to prevent browning.
- Use firm, fresh zucchinis for the best grill marks.
- Dry greens completely to avoid a watery salad.
- Add a sprinkle of fresh herbs like cilantro or parsley for brightness.
- Toss gently to avoid mashing the avocado or greens.
- Optional: a pinch of smoked paprika enhances the smoky flavor of grilled vegetables.
Storage & Make-Ahead
Store leftover grilled vegetables separately in airtight containers in the fridge for up to 2 days. Greens are best kept separate and combined at serving to maintain freshness. Dressing can be made ahead but add only before serving. Avoid storing the assembled salad as the avocado may brown and greens can wilt.
