In a large bowl, combine the spelt flour with the yeast, water, honey, 1 tablespoon of the olive oil and 3/4 teaspoon of kosher salt and stir until a dough forms. Turn the dough out onto a lightly floured surface and knead just until smooth, no more than 1 minute. Oil the bowl and return the dough to it. Let the dough rise, covered, in a warm, draft-free place until doubled in bulk, about 1 hour.

Line a baking sheet with parchment paper. Punch down the dough, then transfer it to the baking sheet and press it into a 12-by-8-inch oval. Brush with 1 teaspoon of the olive oil. Press small indentations all over the dough and sprinkle with the rosemary and sea salt. Let the dough stand uncovered for 45 minutes, until slightly risen. Preheat the oven to 375 degrees. Bake the focaccia for about 30 minutes, until lightly browned all over.

Meanwhile, in a bowl, toss the kale with the lemon juice, crushed red pepper and 1 teaspoon of oil. Squeeze the kale gently to soften it, then let it stand for 20 minutes.

In a large nonstick skillet, heat the remaining 1 teaspoon of oil. Add the squash, season with kosher salt and cook over moderately high heat until golden, 2 minutes. Turn the squash, add the garlic and cook over moderately low heat until the squash is tender, 5 minutes.

Top the focaccia with the kale and squash and bake for 1 minute longer, to heat the vegetables. Scatter the pecorino on top, cut into wedges and serve.
