Preheat oven to 350 degrees. Sprinkle strawberries with 1/2 cup sugar; set aside.
Combine flour, baking soda, cinnamon and salt. Set aside.
In a large bowl, beat eggs with remaining 1/2 cup sugar until fluffy and lemon-colored. Stir in oil and vanilla. Add walnuts and reserved flour mixture. Stir only until combined.
Turn into well-greased and lightly floured 9x5x3-inch loaf pan; spread smooth. Bake until a cake tester inserted in the center comes out clean, about 45 minutes. Remove from pan and cool on a wire rack.
