Place leftover mashed potatoes, eggs, flour, and parmesan in a food processor and mix until a ball is formed. If the dough is sticky add a little more flour, until ball forms.
Shape small portions of the dough into long "snakes". On a floured surface, cut snakes into half-inch pieces.
Bring a big pot of water with salt to a boil. Drop in gnocchi and cook for 3 to 5 minutes or until gnocchi have risen to the top. Use a slotted spoon to remove gnocchi. Set aside on wax paper if you are not ready to add them to the skillet if you are ready just add them to the skillet.
Make Citrus Garlic Pesto
Place fresh Italian Parsley, lemon juice, garlic, orange zest, grated Parmesan cheese, olive oil, almonds, and salt into food processor and blend until everything is finely chopped and incorporated. If mixture appears too thick feel free to add more olive oil.
Everything Comes Together
Heat up water in microwave safe bowl, stir in and dissolve vegetable base in the water.
In cast iron skillet saute the onions in 1/2 tablespoon butter over medium-low heat until slightly translucent. Add in almonds and let them toast and turn a light brown for a few minutes.
Place remaining 1 tablespoon butter into the skillet with onions and almonds. Once melted add in the gnocchi. Allow the gnocchi to fry for 5 minutes, stirring and flipping occasionally.
Add in tomato paste and water with the vegetable base. Stir until well combined.
Add in chopped red pepper, zucchini, yellow squash, and asparagus. Allow all ingredients to cook together for 2 minutes.
Remove cast iron skillet from heat and stir in citrus pesto.
Top with parmesan cheese and sliced almonds and serve.
This recipe takes some multi-tasking here is the order I prep and make Veggie Loaded Parmesan Gnocchi with Citrus Garlic Pesto with no stopping to prep:
Cut up all veggies, juice a lemon, and zest the orange
Get the water boiling for the gnocchi
Chop the onions and add them to skillet with the butter (do not turn the stove on yet)
Make gnocchi dough and roll out and cut half the gnocchi
Turn on stove to get onions going
Finish rolling out and cutting gnocchi
Add almonds to the onions and butter
Add gnocchi to the boiling salt water
Once gnocchi rises to the top I add remaining butter to the skillet and using a slotted spoon place the gnocchi immediately into the skillet and allow to fry up
