Baked Spinach and Artichoke Toasts
Any loaf of French or Italian bread will work just fine for this. You can use a buttery olive oil instead of butter, Cheddar instead of Gruyere, and mozzarella for provolone if you'd like something milder.
If your loaf is a lot more narrow, like a baguette, you'll want to slice it at an angle so your pieces are longer. If using a wide loaf, slices can be cut in half.
If you want to add other veggies to this, go ahead, such as sauteed mushrooms or roasted red peppers.
