To make the sauce, heat a saucepan over medium heat with 2 tbsp of olive oil. Once hot, add the garlic, tomato paste, crushed tomatoes, oregano, and basil. Season with salt and pepper. Bring the mixture to a boil and then down to a simmer. Simmer for 1 hour.
In a bowl, mix all of the ingredients for the black bean salsa. Season with salt and pepper to taste and set aside.
In another bowl, mix the ingredients for the ricotta mixture together until well combined. Set aside.
Once the tomato sauce is done, taste for salt and pepper. Mix the sauce together with the black bean salsa.
Cook the paste in boiling water until al dente. Drain the pasta and set aside.
In a 13x9" pan, spread a thin layer of the tomato sauce mixture. Lay one layer of lasagna noodles, then a layer of ricotta, then a layer of mozzarella and parmesan cheese. Repeat these layers twice ending with the sauce and cheese on top.
Cover with foil and bake for 40 minutes. Remove the foil and bake for another 15 minutes.
