Mix flour, sugar, and pinch of salt together.

Gently place berries in tart pan or 8" square pan, sprinkle with lemon juice, and toss with sugar/flour mixture.

Mix all topping ingredients together, making a crumbly mixture.  Cover berries with crumb topping and bake at 350 degrees for 40-45 minutes, until berries are bubbly and soft.

Serve with vanilla ice cream or whipped cream.

For a vegan version, use soy margarine instead of butter and top with toffuti or rice cream.

Makes 4-6 servings.
