This dish is a warm, herby, cheesy spread that will make you think of avocados in a whole new light. 🥑
Prepare a very hot gas or charcoal grill , or set a grill pan over medium-high heat. Halve, peel and pit the avocados and put them in a medium bowl. Sprinkle with 1 tablespoon each of olive oil and lemon juice. Season lightly with salt and pepper.
Brush the surface of the grill or grill pan with a light coating of oil so the avocados won't stick. Grill the avocados, cut side down, for a minute or two, until they are nicely caramelized. Flip them with a spatula and cook for another 2 minutes. Return the avocados to the bowl and mash gently with a fork, leaving them quite chunky. Stir in the rest of the olive oil, lemon zest, garlic, basil and Parmesan, adding more lemon juice, cheese, salt and pepper to taste.
