Enjoy the rest of last night's pesto with these simple vegetable-based pizzas, which are lighter in calories and provides an umami, meaty flavor. Smarts: Make more of these for freezing. After cooking, let them cool and then place onto a sheet pan and freeze for ~3 hours. Then package them up individually in bags or foil.
Brush portobello mushrooms with olive oil (both sides). Place portobellos cap side down (or stem-side up, even though the stems are gone) on a sheet pan. Spoon pesto into mushrooms. Top with sliced tomatoes and then sprinkle on cheese.
Bake in the oven for 15 to 18 minutes, until cheese is bubbly.
While pizzas are baking, chop peppers and cucumbers. Make vinaigrette if not already done from last night. Whisk together honey, Dijon, vinegar, and olive oil. Season to taste with salt and pepper.
When portobello pizzas are done, toss vinaigrette with peppers, cucumbers, mixed greens, and sliced almonds. Enjoy!
