Remove paper-like outer layers of skin from the garlic bulb.
Cut the top off of the garlic bulb to expose the individual cloves.
Drizzle olive oil on top of the garlic. Wrap in aluminum foil.
Roast for 45 minutes.
Once cool enough to handle, remove from foil and squeeze the garlic out into a bowl.
Squeeze the juice out of the lemon (about 3 Tbsp) and add to the bowl.
Add the mayonnaise and black pepper. Whisk until combined.
Chill for 30 minutes.
Turkey Sliders
Set oven to broil on high. Set rack to medium to low position in your oven.
Place bottom of slider buns onto a cookie sheet. Toast slightly in oven for 1 minute.
Add sliced tomato and spinach to the buns. Return to oven and cook for 2 minutes.
Add turkey and sliced cheese to the buns. Return to oven and cook for 2 minutes. At the same time these are cooking, you will want to toast your top buns directly on the oven rack.
Spread garlic aioli onto top buns and add to sliders.
Serve warm.
Notes
I like to use Pepperidge Farms Potato Slider Buns
Slice each tomato into 4 slices
You can spice these up more by adding dill, cayenne pepper, crushed red pepper, or any other of your favorite spices
